Add function gfs2_withdrawn and replace all checks for the SDF_WITHDRAWN
bit to call it. This does not change the logic or function of gfs2, and
it facilitates later improvements to the withdraw sequence.

The only difference between the two is that gfs2_ordered_aops sets the

__set_page_dirty_buffers is the default, if no method is set, there is no need
to to do that. Merge the two sets of operations into one.

Since commit 64bc06bb32ee ("gfs2: iomap buffered write support"), gfs2 is doing
buffered writes by starting a transaction in iomap_begin, writing a range of
pages, and ending that transaction in iomap_end. This approach suffers from
two problems:
(1) Any allocations necessary for the write are done in iomap_begin, so when
the data aren't journaled, there is no need for keeping the transaction open
until iomap_end.
(2) Transactions keep the gfs2 log flush lock held. When
iomap_file_buffered_write calls balance_dirty_pages, this can end up calling
gfs2_write_inode, which will try to flush the log. This requires taking the
log flush lock which is already held, resulting in a deadlock.
Fix both of these issues by not keeping transactions open from iomap_begin to
iomap_end. Instead, start a small transaction in page_prepare and end it in
page_done when necessary.

The gfs2_is_ordered and gfs2_is_writeback checks are weird in that they
implicitly check for !gfs2_is_jdata. This makes understanding how to
use those functions correctly a challenge. Clean this up by making
gfs2_is_ordered and gfs2_is_writeback take a super block instead of an
inode and by removing the implicit !gfs2_is_jdata checks. Update the
callers accordingly.

With the traditional page-based writes, blocks are allocated separately
for each page written to. With iomap writes, we can allocate a lot more
blocks at once, with a fraction of the allocation overhead for each
page.
Split calculating the number of blocks that can be allocated at a given
position (gfs2_alloc_size) off from gfs2_iomap_alloc: that size
determines the number of blocks to allocate and reserve in the journal.

In journaled data mode, we need to add each buffer head to the current
transaction. In ordered write mode, we only need to add the inode to
the ordered inode list. So far, both cases are handled in
gfs2_trans_add_data. This makes the code look misleading and is
inefficient for small block sizes as well. Handle both cases separately
instead.

Before this patch function gfs2_write_begin, upon discovering an
error, called gfs2_trim_blocks while the rgrp glock was still held.
That's because gfs2_inplace_release is not called until later.
This patch reorganizes the logic a bit so gfs2_inplace_release
is called to release the lock prior to the call to gfs2_trim_blocks,
thus preventing the glock recursion.

Every pagevec_init user claims the pages being released are hot even in
cases where it is unlikely the pages are hot. As no one cares about the
hotness of pages being released to the allocator, just ditch the
parameter.
No performance impact is expected as the overhead is marginal. The
parameter is removed simply because it is a bit stupid to have a useless
parameter copied everywhere.

On systems with low memory, it is possible for gfs2 to infinitely
loop in balance_dirty_pages() under heavy IO (creating sparse files).
balance_dirty_pages() attempts to write out the dirty pages via
gfs2_writepages() but none are found because these dirty pages are
being used by the journaling code in the ail. Normally, the journal
has an upper threshold which when hit triggers an automatic flush
of the ail. But this threshold can be higher than the number of
allowable dirty pages and result in the ail never being flushed.
This patch forces an ail flush when gfs2_writepages() fails to write
anything. This is a good indication that the ail might be holding
some dirty pages.

"We've got eight GFS2 patches for this merge window:
- Andy Price submitted a patch to make gfs2_write_full_page a static

- Dan Carpenter submitted a patch to fix a ERR_PTR thinko.
Three patches fix bugs related to deleting very large files, which
cause GFS2 to run out of journal space:
- The first one prevents GFS2 delete operation from requesting too
much journal space.
- The second one fixes a problem whereby GFS2 can hang because it
wasn't taking journal space demand into its calculations.
- The third one wakes up IO waiters when a flush is done to restart
processes stuck waiting for journal space to become available.
The final three patches are a performance improvement related to
spin_lock contention between multiple writers:
- The "tr_touched" variable was switched to a flag to be more atomic
and eliminate the possibility of some races.
- Function meta_lo_add was moved inline with its only caller to make
the code more readable and efficient.
- Contention on the gfs2_log_lock spinlock was greatly reduced by
avoiding the lock altogether in cases where we don't really need
it: buffers that already appear in the appropriate metadata list
for the journal. Many thanks to Steve Whitehouse for the ideas and
principles behind these patches"

a) the page is uptodate - ->write_begin() would either fail (in which
case we don't reach ->write_end()), or unstuff the inode, or find the
page already uptodate, or do a successful call of stuffed_readpage(),
which would've made it uptodate
b) zeroing the tail in pagecache is wrong. kill -9 at the right time
while writing unmodified file contents to the same file should _not_
leave us in a situation when read() from the file will be reporting
it full of zeroes. Especially since that effect will be transient -
at some later point the page will be evicted and then we'll be back
to the real file contents.

When gfs2 attempts to write a page to a file that is being truncated,
and notices that the page is completely outside of the file size, it
tries to invalidate it. However, this may require a transaction for
journaled data files to revoke any buffers from the page on the active
items list. Unfortunately, this can happen inside a log flush, where a
transaction cannot be started. Also, gfs2 may need to be able to remove
the buffer from the ail1 list before it can finish the log flush.
To deal with this, when writing a page of a file with data journalling
enabled gfs2 now skips the check to see if the write is outside the file
size, and simply writes it anyway. This situation can only occur when
the truncate code still has the file locked exclusively, and hasn't
marked this block as free in the metadata (which happens later in
truc_dealloc). After gfs2 writes this page out, the truncation code
will shortly invalidate it and write out any revokes if necessary.
To do this, gfs2 now implements its own version of block_write_full_page
without the check, and calls the newly exported __block_write_full_page.
It also no longer calls gfs2_writepage_common from gfs2_jdata_writepage.

PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
ago with promise that one day it will be possible to implement page
cache with bigger chunks than PAGE_SIZE.
This promise never materialized. And unlikely will.
We have many places where PAGE_CACHE_SIZE assumed to be equal to
PAGE_SIZE. And it's constant source of confusion on whether
PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
especially on the border between fs and mm.
Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
breakage to be doable.
Let's stop pretending that pages in page cache are special. They are
not.
The changes are pretty straight-forward:
- <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};
- page_cache_get() -> get_page();
- page_cache_release() -> put_page();
This patch contains automated changes generated with coccinelle using
script below. For some reason, coccinelle doesn't patch header files.
I've called spatch for them manually.
The only adjustment after coccinelle is revert of changes to
PAGE_CAHCE_ALIGN definition: we are going to drop it later.
There are few places in the code where coccinelle didn't reach. I'll
fix them manually in a separate patch. Comments and documentation also
will be addressed with the separate patch.

The fsx test in xfstests was failing because it was using direct IO
writes which were using a bad calculation. It was using
loff_t lstart = offset & (PAGE_CACHE_SIZE - 1); when it should be
loff_t lstart = offset & ~(PAGE_CACHE_SIZE - 1);
Thus, the write at offset 0x67e00 was calculating lstart to be

This patch basically reverts the majority of patch 5407e24.
That patch eliminated the gfs2_qadata structure in favor of just
using the reservations structure. The problem with doing that is that
it increases the size of the reservations structure. That is not an
issue until it comes time to fold the reservations structure into the
inode in memory so we know it's always there. By separating out the
quota structure again, we aren't punishing the non-quota users by
making all the inodes bigger, requiring more slab space. This patch
creates a new slab area to allocate the quota stuff so it's managed
a little more sanely.
