This patch fixes the NFS functionality regression by making\nuse of the new LSM interfaces to allow an FS to explicitly set its own\nmount options.\n\nThe explicit setting of mount options is done in the nfs get_sb\nfunctions which are called before the generic vfs hooks try to set mount\noptions for filesystems which use text mount data.\n\nThis does not currently support NFSv4 as that functionality did not\nexist in previous kernels and thus there is no regression.

Consider the\nfollowing series of events in processes A and B:\n\n A) Allocates some surplus pages to satisfy a reservation\n B) Frees some huge pages\n A) A notices the extra free pages and drops hugetlb_lock to free some of\n its surplus pages back to the buddy allocator.\n B) Allocates some huge pages\n A) Reacquires hugetlb_lock and returns from gather_surplus_huge_pages()\n\nAvoid this by commiting the reservation after pages have been allocated but\nbefore dropping the lock to free excess pages. For parity, release the\nreservation in return_unused_surplus_pages().\n\nThis patch also corrects the cpuset_mems_nr() error path in\nhugetlb_acct_memory(). If the cpuset check fails, uncommit the\nreservation, but also be sure to return any surplus huge pages that may\nhave been allocated to back the failed reservation.\n\nThanks to Andy Whitcroft for discovering this.\n\nSigned-off-by: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a07e6ab41be179cf1ed728a4f41368435508b550", "tree": "10773de394ab861259468372099c90b3f8671292", "parents": [ "1c830532f6b44d10a1743ccd00e990c6b83396f5" ], "author": { "name": "K.Tanaka", "email": "k-tanaka@ce.jp.nec.com", "time": "Tue Mar 04 14:29:37 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Mar 04 16:35:18 2008 -0800" }, "message": "md: the md RAID10 resync thread could cause a md RAID10 array deadlock\n\nThis message describes another issue about md RAID10 found by testing the\n2.6.24 md RAID10 using new scsi fault injection framework.\n\nAbstract:\n\nWhen a scsi error results in disabling a disk during RAID10 recovery, the\nresync threads of md RAID10 could stall.\n\nThis case, the raid array has already been broken and it may not matter. But\nI think stall is not preferable. If it occurs, even shutdown or reboot will\nfail because of resource busy.\n\nThe deadlock mechanism:\n\nThe r10bio_s structure has a \"remaining\" member to keep track of BIOs yet to\nbe handled when recovering. The \"remaining\" counter is incremented when\nbuilding a BIO in sync_request() and is decremented when finish a BIO in\nend_sync_write().\n\nIf building a BIO fails for some reasons in sync_request(), the \"remaining\"\nshould be decremented if it has already been incremented. I found a case\nwhere this decrement is forgotten. This causes a md_do_sync() deadlock\nbecause md_do_sync() waits for md_done_sync() called by end_sync_write(), but\nend_sync_write() never calls md_done_sync() because of the \"remaining\" counter\nmismatch.\n\nFor example, this problem would be reproduced in the following case:\n\nPersonalities : [raid10]\nmd0 : active raid10 sdf1[4] sde1[5](F) sdd1[2] sdc1[1] sdb1[6](F)\n 3919616 blocks 64K chunks 2 near-copies [4/2] [_UU_]\n [\u003e....................] recovery \u003d 2.2% (45376/1959808) finish\u003d0.7min speed\u003d45376K/sec\n\nThis case, sdf1 is recovering, sdb1 and sde1 are disabled.\nAn additional error with detaching sdd will cause a deadlock.\n\nmd0 : active raid10 sdf1[4] sde1[5](F) sdd1[6](F) sdc1[1] sdb1[7](F)\n 3919616 blocks 64K chunks 2 near-copies [4/1] [_U__]\n [\u003d\u003e...................] recovery \u003d 5.0% (99520/1959808) finish\u003d5.9min speed\u003d5237K/sec\n\n 2739 ?
