2023-10-22bcachefs: Set the last mount time using the realtime clockTim Schlueter
This way the last mount time is actually meaningful instead of just being various times from 1970 (which happens with the monotonic clock). Also, roundup_pow_of_two() is undefined when passed in 0, so check before calling it. Signed-off-by: Tim Schlueter <schlueter.tim@linux.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-22bcachefs: Assorted fixes for running on very small devicesKent Overstreet
It's now possible to create and use a filesystem on a 512k device with 4k buckets (though at that size we still waste almost half to internal reserves) Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Scale down number of writepoints when low on spaceKent Overstreet
this means we don't have to reserve space for them when calculating filesystem capacity Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-22bcachefs: Some fixes for building in userspaceKent Overstreet
userspace allocators don't align allocations as nicely as kernel allocators, which meant that in some cases we weren't allocating big enough bvec arrays - just make the calculations more rigorous and explicit to fix it. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-22bcachefs: bch2_extent_ptr_decoded_append()Kent Overstreet
This new helper for the move path avoids creating a new CRC entry when we already have one that matches the pointer being added. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-22bcachefs: Allocation code refactoringKent Overstreet
bch2_alloc_sectors_start() was a nightmare to work with - it's got some tricky stuff to do, since it wants to use the buckets the writepoint already has, unless they're not in the target it wants to write to, unless it can't allocate from any other devices in which case it will use those buckets if it has to - et cetera. This restructures the code to start with a new empty list of open buckets we're going to use for the new allocation, pulling buckets from the write point's list as we decide that we really are going to use them - making the code somewhat more functional and drastically easier to understand. Also fixes a bug where we could end up waiting on c->freelist_wait (because allocating from one device failed) but return success from bch2_bucket_alloc(), because allocating from a different device succeeded.

2023-10-22bcachefs: Dirent repair codeKent Overstreet
There was a bug for awhile in previous kernels where we weren't computing dirent name lengths correctly and we weren't zeroing out padding at the end of dirents (due to struct bch_dirent changing size by adding __attribute__((aligned)), and not updating other code to use offsetof). This patch fixes dirents with junk at the end, by going off of the dirent's hash. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
