Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git tags/ovl-update-5.8
There are some changes outside of the overlayfs tree; clone_private_mount()
was reviewed by Al, the rest are trivial. No other filesystems are
affected by these.
Fixes:
- Resolve mount option conflicts consistently.
- Sync before remount R/O.
- Fix file handle encoding corner cases.
- Fix metacopy related issues.
- Fix an unintialized return value.
- Add missing permission checks for underlying layers.
Optimizations:
- Allow multipe whiteouts to share an inode.
- Optimize small writes by inheriting SB_NOSEC from upper layer.
- Do not call ->syncfs() multiple times for sync(2).
- Do not cache negative lookups on upper layer.
- Make private internal mounts longterm.
Thanks,
Miklos
