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"
