While working on a patch series to change how we handle the ctime, I
found a number of places that update the mtime without a corresponding
ctime update. POSIX requires that when the mtime is updated that the
ctime also be updated.

Note that these are largely untested other than for compilation, so
please review carefully. These are a preliminary set for the upcoming
rework of how we handle the ctime.

None of these seem to be very crucial, but it would be nice if
various maintainers could pick these up for v6.5. Please let me know if
you do.

Jeff Layton (9):
  ibmvmc: update ctime in conjunction with mtime on write
  usb: update the ctime as well when updating mtime after an ioctl
  autofs: set ctime as well when mtime changes on a dir
  bfs: update ctime in addition to mtime when adding entries
  efivarfs: update ctime when mtime changes on a write
  exfat: ensure that ctime is updated whenever the mtime is
  gfs2: update ctime when quota is updated
  apparmor: update ctime whenever the mtime changes on an inode
  cifs: update the ctime on a partial page write

It did, once I ran it. ;)

I'll repost the set with more elaborate changelogs.
