Merge tag 'for-6.15-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
- handle encoded read ioctl returning EAGAIN so it does not mistakenly
free the work structure
- escape subvolume path in mount option list so it cannot be wrongly
parsed when the path contains ","
- remove folio size assertions when writing super block to device with
enabled large folios
* tag 'for-6.15-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: remove folio order ASSERT()s in super block writeback path
btrfs: correctly escape subvol in btrfs_show_options()
btrfs: ioctl: don't free iov when btrfs_encoded_read() returns -EAGAIN
