Linus Torvalds 2171ee8f43 NFS client bugfixes for Linux 3.9 ... - Fix an Oops in the pNFS layoutget code - Fix a number of NFSv4 and v4.1 state recovery deadlocks and hangs due to the interaction of the session drain lock and state management locks. - Remove task->tk_xprt, which was hiding a lot of RCU dereferencing bugs - Fix a long standing NFSv3 posix lock recovery bug. - Revert commit 324d003b0c. It turned out that the root cause of the deadlock was due to interactions with the workqueues that have now been resolved. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) iQIcBAABAgAGBQJRJUfVAAoJEGcL54qWCgDySIoP/2QC2qNKqfcoIwOqOAR0pu5m wHybR67WXt/R6EK17l273apHfnJQb/IFFKRBfAIAW0vy4bJLwHMtutIeUweFWht2 hmluYqVWAa9lPwaY1YMolo8Mfizaj0cY3QHv2ogF4poY0SLO6L8O/xo8n8nrn/pk QJW9tcvz43A2tbW92t833sQMFQSSjs9L2tvxM/BEahLrSEE4dl6WMWscmHQ/IXt/ Hs3ADc4//dDF36k5lu7tU0qaVNDacjMXCV6Bw0HUCWCwjWzqmPxSlTDKAcer2vpm UawKDFTF4X1QYwbtGlNju0xhsSGRg7ZNRVEeRxqSROT280nzpp7C3CjM9sECtM2l SR9RqoYfBsEAyWZtsALApuSBZZZHOvUfVJEL1Cm0ZSeEbWSOO/DT07KRVgfb97h4 hmE7pn5htgXdiGN2YCphMjrqjaoP4aKmULenj1h1jHbDOgrlqp2QLWqg/5NxMsTw M3vmYqQWkW60JN6e1pWJbsoyUkSMTVycRNrZ6WgShtd1lrz3tg66rDXYWdIhU6pT 6qAKrkXnM5JkLoMoImNQod00Vr1ZXpVc8DLoFtug8rGohCdFJhWkYHefqVJ9rFhv 2S2NpKDsFiA0q3aK0/YAkUnykYDAnLn7BM5SvhJjq8mKru4bP70PrN9LO8aqhE4E fFgj2MGG5QwrL0/GMuls =dthb -----END PGP SIGNATURE----- Merge tag 'nfs-for-3.9-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs Pull NFS client bugfixes from Trond Myklebust: - Fix an Oops in the pNFS layoutget code - Fix a number of NFSv4 and v4.1 state recovery deadlocks and hangs due to the interaction of the session drain lock and state management locks. - Remove task->tk_xprt, which was hiding a lot of RCU dereferencing bugs - Fix a long standing NFSv3 posix lock recovery bug. - Revert commit 324d003b0c ("NFS: add nfs_sb_deactive_async to avoid deadlock").
