[PATCH] autofs4: readdir fixes
From: Ian Kent <raven@themaw.net>
a. Implement readdir and friends for directory lookup for late mounting.
This is done largely by replacing a catch all condition in
try_to_fill_dentry with appropriate cases.
b. Add path calc. function in waitq.c to get extended path to return to
daemon (for direct mounts).
c. Add revalidate calls to sys_chdir and sys_chroot so that pwd lookups
work correctly.
d. Add ioctl to retrieve minor version for automount daemon (and me) to
recognise module fix level. Bumped minor version to 5.
From: Hugh Dickins <hugh@veritas.com>
After chdir (or chroot) to non-existent directory on 2.6.5-mm5, you can no
longer unmount filesystem holding working directory (or root).
