fs: Convert aops->write_end to take a folio

2024-08-07T09:32:02Z

Most callers have a folio, and most implementations operate on a folio, so remove the conversion from folio->page->folio to fit through this interface. Reviewed-by: Josef Bacik Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Christian Brauner

vboxsf: Use a folio in vboxsf_write_end()

2024-08-07T09:32:02Z

Because we have to kmap() the page before calling vboxsf_write(), we can't entirely remove the use of struct page. But we can eliminate some uses of old APIs and remove some unnecessary calls to compound_head(). Reviewed-by: Josef Bacik Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Christian Brauner

Merge tag 'vfs-6.11.mount.api' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

2024-07-15T18:31:32Z

Pull vfs mount API updates from Christian Brauner: - Add a generic helper to parse uid and gid mount options. Currently we open-code the same logic in various filesystems which is error prone, especially since the verification of uid and gid mount options is a sensitive operation in the face of idmappings. Add a generic helper and convert all filesystems over to it. Make sure that filesystems that are mountable in unprivileged containers verify that the specified uid and gid can be represented in the owning namespace of the filesystem. - Convert hostfs to the new mount api. * tag 'vfs-6.11.mount.api' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fuse: Convert to new uid/gid option parsing helpers fuse: verify {g,u}id mount options correctly fat: Convert to new uid/gid option parsing helpers fat: Convert to new mount api fat: move debug into fat_mount_options vboxsf: Convert to new uid/gid option parsing helpers tracefs: Convert to new uid/gid option parsing helpers smb: client: Convert to new uid/gid option parsing helpers tmpfs: Convert to new uid/gid option parsing helpers ntfs3: Convert to new uid/gid option parsing helpers isofs: Convert to new uid/gid option parsing helpers hugetlbfs: Convert to new uid/gid option parsing helpers ext4: Convert to new uid/gid option parsing helpers exfat: Convert to new uid/gid option parsing helpers efivarfs: Convert to new uid/gid option parsing helpers debugfs: Convert to new uid/gid option parsing helpers autofs: Convert to new uid/gid option parsing helpers fs_parse: add uid & gid option option parsing helpers hostfs: Add const qualifier to host_root in hostfs_fill_super() hostfs: convert hostfs to use the new mount API

vboxsf: Convert vboxsf_read_folio() to use a folio

2024-05-31T10:31:42Z

Remove conversion to a page and use folio APIs throughout. This includes a removal of setting the error flag as nobody checks the error flag on vboxsf folios. This does not include large folio support as we would have to map each page individually.

vboxsf: explicitly deny setlease attempts

2024-04-03T14:06:39Z

vboxsf does not break leases on its own, so it can't properly handle the case where the hypervisor changes the data. Don't allow file leases on vboxsf.

vboxsf: Remove usage of the deprecated ida_simple_xx() API

2024-04-03T14:06:11Z

ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). This is less verbose.

vboxsf: Avoid an spurious warning if load_nls_xxx() fails

2024-04-03T14:05:51Z

If an load_nls_xxx() function fails a few lines above, the 'sbi->bdi_id' is still 0. So, in the error handling path, we will call ida_simple_remove(..., 0) which is not allocated yet. In order to prevent a spurious "ida_free called for id=0 which is not allocated." message, tweak the error handling path and add a new label.

mm, slab: remove last vestiges of SLAB_MEM_SPREAD

2024-03-13T03:32:19Z

Yes, yes, I know the slab people were planning on going slow and letting every subsystem fight this thing on their own. But let's just rip off the band-aid and get it over and done with. I don't want to see a number of unnecessary pull requests just to get rid of a flag that no longer has any meaning. This was mainly done with a couple of 'sed' scripts and then some manual cleanup of the end result.
