Merge tag 'vfs-7.0-rc1.fserror' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs error reporting updates from Christian Brauner:
"This contains the changes to support generic I/O error reporting.
Filesystems currently have no standard mechanism for reporting
metadata corruption and file I/O errors to userspace via fsnotify.
Each filesystem (xfs, ext4, erofs, f2fs, etc.) privately defines
EFSCORRUPTED, and error reporting to fanotify is inconsistent or
absent entirely.
This introduces a generic fserror infrastructure built around struct
super_block that gives filesystems a standard way to queue metadata
and file I/O error reports for delivery to fsnotify.
Errors are queued via mempools and queue_work to avoid holding
filesystem locks in the notification path; unmount waits for pending
events to drain. A new super_operations::report_error callback lets
filesystem drivers respond to file I/O errors themselves (to be used
by an upcoming XFS self-healing patchset).
On the uapi side, EFSCORRUPTED and EUCLEAN are promoted from private
per-filesystem definitions to canonical errno.h values across all
architectures"
* tag 'vfs-7.0-rc1.fserror' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
ext4: convert to new fserror helpers
xfs: translate fsdax media errors into file "data lost" errors when convenient
xfs: report fs metadata errors via fsnotify
iomap: report file I/O errors to the VFS
fs: report filesystem and file I/O errors to fsnotify
uapi: promote EFSCORRUPTED and EUCLEAN to errno.h
