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

Pull second vfs pile from Al Viro: "The stuff in there: fsfreeze deadlock fixes by Jan (essentially, the deadlock reproduced by xfstests 068), symlink and hardlink restriction patches, plus assorted cleanups and fixes. Note that another fsfreeze deadlock (emergency thaw one) is *not* dealt with - the series by Fernando conflicts a lot with Jan's, breaks userland ABI (FIFREEZE semantics gets changed) and trades the deadlock for massive vfsmount leak; this is going to be handled next cycle. There probably will be another pull request, but that stuff won't be in it."

lockd: shift grabbing a reference to nlm_host into nlm_alloc_call()

2012-07-29T19:09:57Z

It's used both for client and server hosts; we can't do nlmclnt_release_host() on failure exits, since the host might need nlmsvc_release_host(), with BUG_ON() for calling the wrong one. Makes life simpler for callers, actually... Signed-off-by: Al Viro

SUNRPC: service request network namespace helper introduced

2012-07-27T20:49:21Z

This is a cleanup patch - makes code looks simplier. It replaces widely used rqstp->rq_xprt->xpt_net by introduced SVC_NET(rqstp). Signed-off-by: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields
