These two patches fix two hard-to-hit (but really annoying) bugs
in
9p.
The first one was posted earlier in February (with one R-b), the
second
is a new one.

Could you apply these? Thanks!

I can pick those, or, if you (or somebody else) are willing to
actively
maintain a 9p tree, you could start sending straight to Linus - up to
you.

You can pick these up, I don't have plans for more patches right now
(unless we hit some new bugs that affect our workloads).

(FWIW there do lurk dragons there, at least 1) setxattr() with zero-
length value turns into a removexattr(), and 2) creat("foo", 0444)
fails due to the R/O perms when opening the writeback_fid. Fixes to
either didn't seem too easy...)

Thanks!
