[PATCH 0/9] fs: add some missing ctime updates

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
