Several fixes; first 4 commits are obvious fixes (a couple
of fdget_pos()-related ones from Eric Biggers, prepend_name() fix, missing
checks for false negatives from __lookup_mnt() in fs/namei.c), followed
by 4 commits dealing with the bug found by Max last week - switch of
mnt_hash to hlist, to avoid the fun with non-terminating __lookup_mnt().
I'm fairly comfortable with that pile, but whether its second part is OK
at this point is up to you; it seems to survive everything I'd thrown
at it, and it's quite straightforward. If you really feel that it's
too close to -final, well... alternative variant is to replace the last
4 with "if we are spinning too much in __lookup_mnt(), check mount_lock"
kludge like the one I've posted early in the "don't clobber mnt_hash.next"
thread. I'd rather go for "let's just use hlist", obviously...
