linux-stable.git/fs/9p, branch v3.3

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs

2012-01-10T23:09:01+00:00

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs:
  fs/9p: iattr_valid flags are kernel internal flags map them to 9p values.
  fs/9p: We should not allocate a new inode when creating hardlines.
  fs/9p: v9fs_stat2inode should update suid/sgid bits.
  9p: Reduce object size with CONFIG_NET_9P_DEBUG
  fs/9p: check schedule_timeout_interruptible return value

Fix up trivial conflicts in fs/9p/{vfs_inode.c,vfs_inode_dotl.c} due to
debug messages having changed to use p9_debug() on one hand, and the
changes for umode_t on the other.

fs/9p: iattr_valid flags are kernel internal flags map them to 9p values.

2012-01-06T16:26:07+00:00

Kernel internal values can change, add protocol values for these constant
and use them.

fs/9p: We should not allocate a new inode when creating hardlines.

2012-01-05T16:51:44+00:00

Don't do new_inode_from fid in case of hardlink creation. This ensures
that link count for hardlink files get updated properly. Earlier link count
was not updated on removing a hardlink with cache mode enabled.

fs/9p: v9fs_stat2inode should update suid/sgid bits.

2012-01-05T16:51:44+00:00

Create a new helper that update the permission bits and use
that, instead of opencoding the logic.

9p: Reduce object size with CONFIG_NET_9P_DEBUG

2012-01-05T16:51:44+00:00

Reduce object size by deduplicating formats.

Use vsprintf extension %pV.
Rename P9_DPRINTK uses to p9_debug, align arguments.
Add function for _p9_debug and macro to add __func__.
Add missing "\n"s to p9_debug uses.
Remove embedded function names as p9_debug adds it.
Remove P9_EPRINTK macro and convert use to pr_.
Add and use pr_fmt and pr_.

fs/9p: check schedule_timeout_interruptible return value

2012-01-05T16:51:44+00:00

In v9fs_file_do_lock() we need to check return value of
schedule_timeout_interruptible() and exit the loop when it
returns nonzero, otherwise the loop is not really interruptible
and after the signal, the loop is no longer throttled by
P9_LOCK_TIMEOUT.

9p: don't bother with unixmode2p9mode() for link() and symlink()

2012-01-04T03:54:58+00:00

	Pass perm to v9fs_vfs_mkspecial() instead of passing mode;
calculate in caller when done for mknod(), use known value for link()
and symlink().  As the result, we avoid a bit of work *and* stop
mixing mode_t with P9_DMLINK.

switch ->create() to umode_t

2012-01-04T03:54:53+00:00

vfs_create() ignores everything outside of 16bit subset of its
mode argument; switching it to umode_t is obviously equivalent
and it's the only caller of the method
