9p: Modify struct v9fs_session_info to use a kuids and kgids

2013-02-12T11:19:33+00:00

Change struct v9fs_session_info and the code that popluates it to use
kuids and kgids.  When parsing the 9p mount options convert the
dfltuid, dflutgid, and the session uid from the current user namespace
into kuids and kgids.  Modify V9FS_DEFUID and V9FS_DEFGUID to be kuid
and kgid values.

use kuid_t's instead of uid_t.

9p: Transmit kuid and kgid values

2013-02-12T11:19:30+00:00

Modify the p9_client_rpc format specifiers of every function that
directly transmits a uid or a gid from 'd' to 'u' or 'g' as
appropriate.

Modify those same functions to take kuid_t and kgid_t parameters
instead of uid_t and gid_t parameters.

fs: push rcu_barrier() from deactivate_locked_super() to filesystems

2012-10-03T01:35:55+00:00

There's no reason to call rcu_barrier() on every
deactivate_locked_super().  We only need to make sure that all delayed rcu
free inodes are flushed before we destroy related cache.

Removing rcu_barrier() from deactivate_locked_super() affects some fast
paths.  E.g.  on my machine exit_group() of a last process in IPC
namespace takes 0.07538s.  rcu_barrier() takes 0.05188s of that time.

9p: don't use getname/putname for uname/aname

2012-09-17T19:54:10+00:00

These are generally very small strings. We don't need an entire 4k
allocation for each. Instead, just free and reallocate them on an
as-needed basis.

Note: This patch is untested since I don't have a 9p server available at
the moment. It's mainly something I noticed while doing some
getname/putname cleanup work.
