Several fixes; a couple of fdget_pos()-related ones from Eric Biggers,
prepend_name() fix (bug was reported by many people, Imre and Jan being the
ones I'd been able to find addresses of), plus a series of fixes for bug
found by Max Kellermann - missing checks for false negatives from
__lookup_mnt() in fs/namei.c + switching mnt_hash to hlist, turning
the races between __lookup_mnt() and hash modifications into
false negatives from __lookup_mnt() (instead of hangs).
Please, pull from the usual place -
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus
Commit ID of that branch should be 7fc5aaa083922420e2dec5d985420cb5f959b1ce;
diffs are the same as what sat there since last Sunday, commit messages
got updated a bit. Should've propagated by now...
Shortlog:
Al Viro (6):
make prepend_name() work correctly when called with negative *buflen
rcuwalk: recheck mount_lock after mountpoint crossing attempts
resizable namespace.c hashes
keep shadowed vfsmounts together
don't bother with propagate_mnt() unless the target is shared
switch mnt_hash to hlist
Eric Biggers (2):
vfs: atomic f_pos access in llseek()
vfs: Don't let __fdget_pos() get FMODE_PATH files
