      "message": "jbd: Fix oops in journal_remove_journal_head()\n\njournal_remove_journal_head() can oops when trying to access journal_head\nreturned by bh2jh(). This is caused for example by the following race:\n\n\tTASK1\t\t\t\t\tTASK2\n  journal_commit_transaction()\n    ...\n    processing t_forget list\n      __journal_refile_buffer(jh);\n      if (!jh-\u003eb_transaction) {\n        jbd_unlock_bh_state(bh);\n\t\t\t\t\tjournal_try_to_free_buffers()\n\t\t\t\t\t  journal_grab_journal_head(bh)\n\t\t\t\t\t  jbd_lock_bh_state(bh)\n\t\t\t\t\t  __journal_try_to_free_buffer()\n\t\t\t\t\t  journal_put_journal_head(jh)\n        journal_remove_journal_head(bh);\n\njournal_put_journal_head() in TASK2 sees that b_jcount \u003d\u003d 0 and buffer is not\npart of any transaction and thus frees journal_head before TASK1 gets to doing\nso. Note that even buffer_head can be released by try_to_free_buffers() after\njournal_put_journal_head() which adds even larger opportunity for oops (but I\ndidn\u0027t see this happen in reality).\n\nFix the problem by making transactions hold their own journal_head reference\n(in b_jcount). That way we don\u0027t have to remove journal_head explicitely via\njournal_remove_journal_head() and instead just remove journal_head when\nb_jcount drops to zero. The result of this is that [__]journal_refile_buffer(),\n[__]journal_unfile_buffer(), and __journal_remove_checkpoint() can free\njournal_head which needs modification of a few callers. Also we have to be\ncareful because once journal_head is removed, buffer_head might be freed as\nwell. So we have to get our own buffer_head reference where it matters.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n"

      "message": "[PATCH] Cleanup patch for process freezing\n\n1. Establish a simple API for process freezing defined in linux/include/sched.h:\n\n   frozen(process)\t\tCheck for frozen process\n   freezing(process)\t\tCheck if a process is being frozen\n   freeze(process)\t\tTell a process to freeze (go to refrigerator)\n   thaw_process(process)\tRestart process\n   frozen_process(process)\tProcess is frozen now\n\n2. Remove all references to PF_FREEZE and PF_FROZEN from all\n   kernel sources except sched.h\n\n3. Fix numerous locations where try_to_freeze is manually done by a driver\n\n4. Remove the argument that is no longer necessary from two function calls.\n\n5. Some whitespace cleanup\n\n6. Clear potential race in refrigerator (provides an open window of PF_FREEZE\n   cleared before setting PF_FROZEN, recalc_sigpending does not check\n   PF_FROZEN).\n\nThis patch does not address the problem of freeze_processes() violating the rule\nthat a task may only modify its own flags by setting PF_FREEZE. This is not clean\nin an SMP environment. freeze(process) is therefore not SMP safe!\n\nSigned-off-by: Christoph Lameter \u003cchristoph@lameter.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
