Since the file is no longer persistent, all references to the\nterm persistent file are changed to lower file.\n\nLocking is added around the sections of code that opens the lower file\nand assign the pointer in the inode info, as well as the code the fputs\nthe lower file when all eCryptfs users are done with it.\n\nThis patch is needed to fix issues, when mounted on top of the NFSv3\nclient, where the lower file is left silly renamed until the eCryptfs\ninode is destroyed.\n\nSigned-off-by: Tyler Hicks \u003ctyhicks@linux.vnet.ibm.com\u003e\n" }, { "commit": "dd55c89852481a0708c3fd4b48f3081f4280d9d3", "tree": "36e516d3802f5854a9e25610bdfd2382f497ef0d", "parents": [ "35ffa948b2f7bdf79e488cd496232935d095087a" ], "author": { "name": "Tyler Hicks", "email": "tyhicks@linux.vnet.ibm.com", "time": "Tue Apr 12 11:23:09 2011 -0500" }, "committer": { "name": "Tyler Hicks", "email": "tyhicks@linux.vnet.ibm.com", "time": "Mon Apr 25 18:32:36 2011 -0500" }, "message": "eCryptfs: dput dentries returned from dget_parent\n\nCall dput on the dentries previously returned by dget_parent() in\necryptfs_rename().

That made functions like __d_drop() very fragile\nand non-obvious.\n\nIn particular, whether a dentry was hashed or not was indicated with an\nexplicit DCACHE_UNHASHED bit. That\u0027s despite the fact that the hash\nabstraction that the dentries use actually have a \u0027is this entry hashed\nor not\u0027 model (which is a simple test of the \u0027pprev\u0027 pointer).\n\nThe reason that was done is because we used the normal \u0027is this entry\nunhashed\u0027 model to mark whether the dentry had _ever_ been hashed in the\ndentry hash tables, and that logic goes back many years (commit\nb3423415fbc2: \"dcache: avoid RCU for never-hashed dentries\").\n\nThat, in turn, meant that __d_drop had totally different unhashing logic\nfor the dentry hash table case and for the anonymous dcache case,\nbecause in order to use the \"is this dentry hashed\" logic as a flag for\nwhether it had ever been on the RCU hash table, we had to unhash such a\ndentry differently so that we\u0027d never think that it wasn\u0027t \u0027unhashed\u0027\nand wouldn\u0027t be free\u0027d correctly.\n\nThat\u0027s just insane. It made the logic really hard to follow, when there\nwere two different kinds of \"unhashed\" states, and one of them (the one\nthat used \"list_bl_unhashed()\") really had nothing at all to do with\nbeing unhashed per se, but with a very subtle lifetime rule instead.\n\nSo turn all of it around, and make it logical.\n\nInstead of having a DENTRY_UNHASHED bit in d_flags to indicate whether\nthe dentry is on the hash chains or not, use the hash chain unhashed\nlogic for that. Suddenly \"d_unhashed()\" just uses \"list_bl_unhashed()\",\nand everything makes sense.\n\nAnd for the lifetime rule, just use an explicit DENTRY_RCUACCEES bit.\nIf we ever insert the dentry into the dentry hash table so that it is\nvisible to RCU lookup, we mark it DENTRY_RCUACCESS to show that it now\nneeds the RCU lifetime rules. Now suddently that test at dentry free\ntime makes sense too.\n\nAnd because unhashing now is sane and doesn\u0027t depend on where the dentry\ngot unhashed from (because the dentry hash chain details doesn\u0027t have\nsome subtle side effects), we can re-unify the __d_drop() logic and use\ncommon code for the unhashing.\n\nAlso fix one more open-coded hash chain bit_spin_lock() that I missed in\nthe previous chain locking cleanup commit.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "686c4cbb10fc0e75b29b097290b4f7fc3f010b9e", "tree": "3361f14eee716d5512a0c423ec89631a5b976ef4", "parents": [ "b07ad9967f40b164af77205027352ba53729cf5a", "19234c0819da0e043a02710488dfd9b242b42eba" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 23 22:35:16 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 23 22:35:16 2011 -0700" }, "message": "Merge branch \u0027pm-fixes\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6\n\n* \u0027pm-fixes\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6:\n PM: Add missing syscore_suspend() and syscore_resume() calls\n PM: Fix error code paths executed after failing syscore_suspend()\n" }, { "commit": "b07ad9967f40b164af77205027352ba53729cf5a", "tree": "33ce9c53602f1983cff5dd5f209bb668fb7ffca5", "parents": [ "0f1d9f78ce41a8874d30271ef8480e6f8f7f1fce" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 23 22:32:03 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 23 22:32:03 2011 -0700" }, "message": "vfs: get rid of \u0027struct dcache_hash_bucket\u0027 abstraction\n\nIt\u0027s a useless abstraction for \u0027hlist_bl_head\u0027, and it doesn\u0027t actually\nhelp anything - quite the reverse.

They are particularly useful in NUMA systems.\n\nWe want to support them via generalized DRAM events: either as the\nfourth level of cache (after the last-level cache), or as a separate\ngeneralization category.\n\nThat way user-space support would be very obvious, memory access\nprofiling could be done via self-explanatory commands like:\n\n perf record -e dram ./myapp\n perf record -e dram-remote ./myapp\n\n... to measure DRAM accesses or more expensive cross-node NUMA DRAM\naccesses.\n\nThese generalized events would work on all CPUs and architectures that\nhave comparable PMU features.\n\n( Note, these are just examples: actual implementation could have more\n sophistication and more parameter - as long as they center around\n similarly simple usecases. )\n\nNow we do not want to revert *all* of the current offcore bits, as they\nare still somewhat useful for generic last-level-cache events, implemented\nin this commit:\n\n e994d7d23a0b: perf: Fix LLC-* events on Intel Nehalem/Westmere\n\nBut we definitely do not yet want to expose the unstructured raw events\nto user-space, until better generalization and usability is implemented\nfor these hardware event features.\n\n( Note: after generalization has been implemented raw offcore events can be\n supported as well: there can always be an odd event that is marginally\n useful but not useful enough to generalize. DRAM profiling is definitely\n *not* such a category so generalization must be done first. )\n\nFurthermore, PERF_TYPE_RAW access to these registers was not intended\nto go upstream without proper support - it was a side-effect of the above\ne994d7d23a0b commit, not mentioned in the changelog.\n\nAs v2.6.39 is nearing release we go for the simplest approach: disable\nthe PERF_TYPE_RAW offcore hack for now, before it escapes into a released\nkernel and becomes an ABI.\n\nOnce proper structure is implemented for these hardware events and users\nare offered usable solutions we can revisit this issue.\n\nReported-by: Andi Kleen \u003cak@linux.intel.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nLink: http://lkml.kernel.org/r/1302658203-4239-1-git-send-email-andi@firstfloor.org\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "b2508e828d71baacd9a743dd48dcbf85d96affdd", "tree": "b0ee8d7d47d8081396643dc6fe8b52ffe6bf6d07", "parents": [ "91e8549bde9e5cc88c5a2e8c8114389279e240b5" ], "author": { "name": "Andi Kleen", "email": "ak@linux.intel.com", "time": "Thu Apr 21 16:48:35 2011 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 22 08:27:29 2011 +0200" }, "message": "perf: Support Xeon E7\u0027s via the Westmere PMU driver\n\nThere\u0027s a new model number public, 47, for Xeon E7 (aka Westmere EX).\n\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nCc: a.p.zijlstra@chello.nl\nLink: http://lkml.kernel.org/r/1303429715-10202-1-git-send-email-andi@firstfloor.org\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "91e8549bde9e5cc88c5a2e8c8114389279e240b5", "tree": "5d5432c2a8a066ecf92e0eec9f07e8b96a6be198", "parents": [ "37fc67c9f0454f7a6448d87225cfee8067fd731d", "7eec77a1816a7042591a6cbdb4820e9e7ebffe0e" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 21 10:50:56 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 21 10:50:56 2011 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block\n\n* \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block:\n ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd\n block: don\u0027t propagate unlisted DISK_EVENTs to userland\n elevator: check for ELEVATOR_INSERT_SORT_MERGE in !elvpriv case too\n" }, { "commit": "7eec77a1816a7042591a6cbdb4820e9e7ebffe0e", "tree": "138c0ed198471151e2590fc3d35f56c5d57ba720", "parents": [ "7c88a168da8003fd4d8fb6ae103c4ecf29cb1130" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Thu Apr 21 19:43:59 2011 +0200" }, "committer": { "name": "Jens Axboe", "email": "jaxboe@fusionio.com", "time": "Thu Apr 21 19:43:59 2011 +0200" }, "message": "ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd\n\ncheck_events() implementations in both ide-gd and ide-cd are\ninadequate for in-kernel event polling.
