Commit 5c521830 (ext4: Support discard requests when running in no-journal mode) attempts to add sb_issue_discard() for data blocks (in data=writeback mode) and in no-journal mode. Unfortunately, this no longer works, because in commit dd3932ed (block: remove BLKDEV_IFL_WAIT), sb_issue_discard() only presents a synchronous interface, and there are times when we call ext4_free_blocks() when we are are holding a spinlock, or are otherwise in an atomic context. For now, I've removed the call to sb_issue_discard() to prevent a deadlock or (if spinlock debugging is enabled) failures like this: BUG: scheduling while atomic: rc.sysinit/1376/0x00000002 Pid: 1376, comm: rc.sysinit Not tainted 2.6.36-ARCH #1 Call Trace: [<ffffffff810397ce>] __schedule_bug+0x5e/0x70 [<ffffffff81403110>] schedule+0x950/0xa70 [<ffffffff81060bad>] ? insert_work+0x7d/0x90 [<ffffffff81060fbd>] ? queue_work_on+0x1d/0x30 [<ffffffff81061127>] ? queue_work+0x37/0x60 [<ffffffff8140377d>] schedule_timeout+0x21d/0x360 [<ffffffff812031c3>] ? generic_make_request+0x2c3/0x540 [<ffffffff81402680>] wait_for_common+0xc0/0x150 [<ffffffff81041490>] ? default_wake_function+0x0/0x10 [<ffffffff812034bc>] ? submit_bio+0x7c/0x100 [<ffffffff810680a0>] ? wake_bit_function+0x0/0x40 [<ffffffff814027b8>] wait_for_completion+0x18/0x20 [<ffffffff8120a969>] blkdev_issue_discard+0x1b9/0x210 [<ffffffff811ba03e>] ext4_free_blocks+0x68e/0xb60 [<ffffffff811b1650>] ? __ext4_handle_dirty_metadata+0x110/0x120 [<ffffffff811b098c>] ext4_ext_truncate+0x8cc/0xa70 [<ffffffff810d713e>] ? pagevec_lookup+0x1e/0x30 [<ffffffff81191618>] ext4_truncate+0x178/0x5d0 [<ffffffff810eacbb>] ? unmap_mapping_range+0xab/0x280 [<ffffffff810d8976>] vmtruncate+0x56/0x70 [<ffffffff811925cb>] ext4_setattr+0x14b/0x460 [<ffffffff811319e4>] notify_change+0x194/0x380 [<ffffffff81117f80>] do_truncate+0x60/0x90 [<ffffffff811e08fa>] ? security_inode_permission+0x1a/0x20 [<ffffffff811eaec1>] ? tomoyo_path_truncate+0x11/0x20 [<ffffffff81127539>] do_last+0x5d9/0x770 [<ffffffff811278bd>] do_filp_open+0x1ed/0x680 [<ffffffff8140644f>] ? page_fault+0x1f/0x30 [<ffffffff81132bfc>] ? alloc_fd+0xec/0x140 [<ffffffff81118db1>] do_sys_open+0x61/0x120 [<ffffffff81118e8b>] sys_open+0x1b/0x20 [<ffffffff81002e6b>] system_call_fastpath+0x16/0x1b https://bugzilla.kernel.org/show_bug.cgi?id=22302Reported-by:

The following BUG can occur when an inode which is getting freed when it still has dirty pages outstanding, and it gets deleted (in this because it was the target of a rename). In ordered mode, we need to make sure the data pages are written just in case we crash before the rename (or unlink) is committed. If the inode is being freed then when we try to igrab the inode, we end up tripping the BUG_ON at fs/ext4/page-io.c:146. To solve this problem, we need to keep track of the number of io callbacks which are pending, and avoid destroying the inode until they have all been completed. That way we don't have to bump the inode count to keep the inode from being destroyed; an approach which doesn't work because the count could have already been dropped down to zero before the inode writeback has started (at which point we're not allowed to bump the count back up to 1, since it's already started getting freed). Thanks to Dave Chinner for suggesting this approach, which is also used by XFS. kernel BUG at /scratch_space/linux-2.6/fs/ext4/page-io.c:146!

Sometimes it is possible and reasonable to adjust the parent clock rate to improve precision of the child clock, e.g., if the child clock has no siblings. clk_round_parent() is a new addition to the SH clock-framework API, that implements such an optimization for child clocks with divisors, taking all integer values in a range.

While scanning the floopy code due to c093ee4f ("floppy: fix use-after-free in module load failure path"), I found one more instance of trying to access disk->queue pointer after doing put_disk() on gendisk. For some reason , floppy moule still loads/unloads fine. The object is probably still around with right pointer values. o There seems to be one more instance of trying to cleanup the request queue after we have called put_disk() on associated gendisk. o This fix is more out of code inspection.

Commit 27ae60f8 ("ipw2x00: replace "ieee80211" with "libipw" where appropriate") changed DRV_NAME to be "libipw", but didn't properly fix up the places where it was used to specify the name for the /proc/net/ directory. For backwards compatibility reasons, that directory name remained "ieee80211", but due to the DRV_NAME change, the error case printouts and the cleanup functions now used "libipw" instead. Which made it all fail badly. For example, on module unload as reported by Randy: WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e() name 'libipw' because it's trying to unregister a /proc directory that obviously doesn't even exist. Clean it all up to use DRV_PROCNAME for the actual /proc directory name. Reported-and-tested-by:

posix-cpu-timers.c correctly assumes that the dying process does posix_cpu_timers_exit_group() and removes all !CPUCLOCK_PERTHREAD timers from signal->cpu_timers list. But, it also assumes that timer->it.cpu.task is always the group leader, and thus the dead ->task means the dead thread group. This is obviously not true after de_thread() changes the leader. After that almost every posix_cpu_timer_ method has problems. It is not simple to fix this bug correctly. First of all, I think that timer->it.cpu should use struct pid instead of task_struct. Also, the locking should be reworked completely. In particular, tasklist_lock should not be used at all. This all needs a lot of nontrivial and hard-to-test changes. Change __exit_signal() to do posix_cpu_timers_exit_group() when the old leader dies during exec. This is not the fix, just the temporary hack to hide the problem for 2.6.37 and stable. IOW, this is obviously wrong but this is what we currently have anyway: cpu timers do not work after mt exec. In theory this change adds another race. The exiting leader can detach the timers which were attached to the new leader. However, the window between de_thread() and release_task() is small, we can pretend that sys_timer_create() was called before de_thread(). Signed-off-by:

It leads to leaking of contents of kernel stack memory. We have to initialize them to zero. In patch v1 Jan Kiszka suggested to fill reserved fields with zeros instead of memset'ting the whole struct. It makes sense as these fields are explicitly marked as padding.
