Merge tag 'vfs-6.9-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fixes from Christian Brauner: "This contains a few small fixes. This comes with some delay because I wanted to wait on people running their reproducers and the Easter Holidays meant that those replies came in a little later than usual: - Fix handling of preventing writes to mounted block devices. Since last kernel we allow to prevent writing to mounted block devices provided CONFIG_BLK_DEV_WRITE_MOUNTED isn't set and the block device is opened with restricted writes. When we switched to opening block devices as files we altered the mechanism by which we recognize when a block device has been opened with write restrictions. The detection logic assumed that only read-write mounted filesystems would apply write restrictions to their block devices from other openers. That of course is not true since it also makes sense to apply write restrictions for filesystems that are read-only. Fix the detection logic using an FMODE_* bit. We still have a few left since we freed up a couple a while ago. I also picked up a patch to free up four additional FMODE_* bits scheduled for the next merge window. - Fix counting the number of writers to a block device. This just changes the logic to be consistent. - Fix a bug in aio causing a NULL pointer derefernce after we implemented batched processing in aio. - Finally, add the changes we discussed that allows to yield block devices early even though file closing itself is deferred. This also allows us to remove two holder operations to get and release the holder to align lifetime of file and holder of the block device" * tag 'vfs-6.9-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: aio: Fix null ptr deref in aio_complete() wakeup fs,block: yield devices early block: count BLK_OPEN_RESTRICT_WRITES openers block: handle BLK_OPEN_RESTRICT_WRITES correctly
