An oplock\nbreak job had raced with a umount, and the superblock got torn down and\nits memory reused. When the oplock break job tried to dereference the\ninode-\u003ei_sb, the kernel oopsed.\n\nThis patchset has the oplock break job hold an inode and vfsmount\nreference until the oplock break completes. With this, there should be\nno need to take a tcon reference (the vfsmount implicitly holds one\nalready).\n\nCurrently, when an oplock break comes in there\u0027s a chance that the\noplock break job won\u0027t occur if the allocation of the oplock_q_entry\nfails. There are also some rather nasty races in the allocation and\nhandling these structs.\n\nRather than allocating oplock queue entries when an oplock break comes\nin, add a few extra fields to the cifsFileInfo struct.

This is broken for a dozen\nreasons, and just doesn\u0027t work in any sort of robust way.\n\nI\u0027m replacing it with the use of a 0 RLIMIT_CORE value. Since helper apps\nset RLIMIT_CORE to zero, we don\u0027t write out core files for any process\nwith that particular limit set. It the core_pattern is a pipe, any\nnon-zero limit is translated to RLIM_INFINITY.\n\nThis allows complete dumps to be captured, but prevents infinite recursion\nin the event that the core_pattern process itself crashes.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nReported-by: Earl Chew \u003cearl_chew@agilent.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ef1ff6b8c08954bc203b59e887d1e580dd91755a", "tree": "6bffcfc02cb57087362defe4cf045c6f70f62a6d", "parents": [ "2c6854fdadf940678fd54779b778f6faafb870bb" ], "author": { "name": "From: Mel Gorman", "email": "mel@csn.ul.ie", "time": "Wed Sep 23 15:56:05 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 24 07:20:56 2009 -0700" }, "message": "hugetlbfs: do not call user_shm_lock() for MAP_HUGETLB fix\n\nCommit 6bfde05bf5c (\"hugetlbfs: allow the creation of files suitable for\nMAP_PRIVATE on the vfs internal mount\") altered can_do_hugetlb_shm() to\ncheck if a file is being created for shared memory or mmap().
