Independent processes\naccessing the same file synchronize over a single lock, even though\nthey have no need for synchronization at all.\n\nUnder high utilization this can cause llseek to scale very poorly on larger\nsystems.\n\nThis patch does some rethinking of the llseek locking model:\n\nFirst the 64bit f_pos is not necessarily atomic without locks\non 32bit systems. This can already cause races with read() today.\nThis was discussed on linux-kernel in the past and deemed acceptable.\nThe patch does not change that.\n\nLet\u0027s look at the different seek variants:\n\nSEEK_SET: Doesn\u0027t really need any locking.\nIf there\u0027s a race one writer wins, the other loses.\n\nFor 32bit the non atomic update races against read()\nstay the same. Without a lock they can also happen\nagainst write() now. The read() race was deemed\nacceptable in past discussions, and I think if it\u0027s\nok for read it\u0027s ok for write too.\n\n\u003d\u003e Don\u0027t need a lock.\n\nSEEK_END: This behaves like SEEK_SET plus it reads\nthe maximum size too. Reading the maximum size would have the\n32bit atomic problem. But luckily we already have a way to read\nthe maximum size without locking (i_size_read), so we\ncan just use that instead.\n\nWithout i_mutex there is no synchronization with write() anymore,\nhowever since the write() update is atomic on 64bit it just behaves\nlike another racy SEEK_SET. On non atomic 32bit it\u0027s the same\nas SEEK_SET.\n\n\u003d\u003e Don\u0027t need a lock, but need to use i_size_read()\n\nSEEK_CUR: This has a read-modify-write race window\non the same file. One could argue that any application\ndoing unsynchronized seeks on the same file is already broken.\nBut for the sake of not adding a regression here I\u0027m\nusing the file-\u003ef_lock to synchronize this. Using this\nlock is much better than the inode mutex because it doesn\u0027t\nsynchronize between processes.\n\n\u003d\u003e So still need a lock, but can use a f_lock.\n\nThis patch implements this new scheme in generic_file_llseek.\nI dropped generic_file_llseek_unlocked and changed all callers.\n\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "ef78cc75f11ba3b085b105209cbfc6666ee10499", "tree": "1820dbd8ebb422b0a5751981cdfb6a2ecd30e20b", "parents": [ "1442d1678ca7e53574fd403ba7bee6f4125d920c", "940aab490215424a269f93d2eba2794fc8b3e269" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 25 15:44:06 2011 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 25 15:44:06 2011 +0200" }, "message": "Merge branch \u0027nfs-for-3.2\u0027 of git://git.linux-nfs.org/projects/trondmy/linux-nfs\n\n* \u0027nfs-for-3.2\u0027 of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (26 commits)\n Check validity of cl_rpcclient in nfs_server_list_show\n NFS: Get rid of the nfs_rdata_mempool\n NFS: Don\u0027t rely on PageError in nfs_readpage_release_partial\n NFS: Get rid of unnecessary calls to ClearPageError() in read code\n NFS: Get rid of nfs_restart_rpc()\n NFS: Get rid of the unused nfs_write_data-\u003eflags field\n NFS: Get rid of the unused nfs_read_data-\u003eflags field\n NFSv4: Translate NFS4ERR_BADNAME into ENOENT when applied to a lookup\n NFS: Remove the unused \"lookupfh()\" version of nfs4_proc_lookup()\n NFS: Use the inode-\u003ei_version to cache NFSv4 change attribute information\n SUNRPC: Remove unnecessary export of rpc_sockaddr2uaddr\n SUNRPC: Fix rpc_sockaddr2uaddr\n nfs/super.c: local functions should be static\n pnfsblock: fix writeback deadlock\n pnfsblock: fix NULL pointer dereference\n pnfs: recoalesce when ld read pagelist fails\n pnfs: recoalesce when ld write pagelist fails\n pnfs: make _set_lo_fail generic\n pnfsblock: add missing rpc_put_mount and path_put\n SUNRPC/NFS: make rpc pipe upcall generic\n ...\n" }, { "commit": "1442d1678ca7e53574fd403ba7bee6f4125d920c", "tree": "fd053a849158d2c5b8345ced8982108825b85736", "parents": [ "7e0bb71e75020348bee523720a0c2f04cc72f540", "345c284290cabb5484df909303e73d6def8ec8ec" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 25 15:42:01 2011 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 25 15:42:01 2011 +0200" }, "message": "Merge branch \u0027for-3.2\u0027 of git://linux-nfs.org/~bfields/linux\n\n* \u0027for-3.2\u0027 of git://linux-nfs.org/~bfields/linux: (103 commits)\n nfs41: implement DESTROY_CLIENTID operation\n nfsd4: typo logical vs bitwise negate for want_mask\n nfsd4: allow NFS4_SHARE_SIGNAL_DELEG_WHEN_RESRC_AVAIL | NFS4_SHARE_PUSH_DELEG_WHEN_UNCONTENDED\n nfsd4: seq-\u003estatus_flags may be used unitialized\n nfsd41: use SEQ4_STATUS_BACKCHANNEL_FAULT when cb_sequence is invalid\n nfsd4: implement new 4.1 open reclaim types\n nfsd4: remove unneeded CLAIM_DELEGATE_CUR workaround\n nfsd4: warn on open failure after create\n nfsd4: preallocate open stateid in process_open1()\n nfsd4: do idr preallocation with stateid allocation\n nfsd4: preallocate nfs4_file in process_open1()\n nfsd4: clean up open owners on OPEN failure\n nfsd4: simplify process_open1 logic\n nfsd4: make is_open_owner boolean\n nfsd4: centralize renew_client() calls\n nfsd4: typo logical vs bitwise negate\n nfs: fix bug about IPv6 address scope checking\n nfsd4: more robust ignoring of WANT bits in OPEN\n nfsd4: move name-length checks to xdr\n nfsd4: move access/deny validity checks to xdr code\n ...\n" }, { "commit": "940aab490215424a269f93d2eba2794fc8b3e269", "tree": "6dec5a3d9476fd3c409d7a73040e0eafb1eba756", "parents": [ "b6ee8cd2642f6d822dd1a4ba62298b65ff99b72e" ], "author": { "name": "Malahal Naineni", "email": "malahal@us.ibm.com", "time": "Tue Sep 20 17:27:14 2011 -0700" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Thu Oct 20 18:44:04 2011 -0500" }, "message": "Check validity of cl_rpcclient in nfs_server_list_show\n\nAs soon as the nfs_client gets created, its cl_rpcclient is set to\nERR_PTR(-EINVAL).
