Change the config to use TEST_START where the options after a TEST_START automatically get the [] as it is read and they do not need to exist in the config file; TEST_START MIN_CONFIG = myconfig is the same as MIN_CONFIG[1] = myconfig The benefit is that you no longer need to keep track of test numbers with tests. Also process the commit ids that are passed to the options to get the actually SHA1 so it is no longer relative to the branch. Ie, saying HEAD will get the current SHA1 and then that will be used, and will work even if another branch is checked out. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

Add a POST_INSTALL option that runs after the build and install but before rebooting to the test kernel. This alls the user to run a script that will install an initrd (or anything else that may be special) before booting. An environment variable KERNEL_VERSION is set.

It is much better to keep the monitor running throughout a test than to constantly start and stop it. Some console readers will show everything that has happened before when opening the console, and by opening it several times, causes the old content to be read multiple times in a single test.

As pointed out by Linus, commit dab5855b ("perf_counter: Add mmap event hooks to mprotect()") is fundamentally wrong as mprotect_fixup() can free 'vma' due to merging. Fix the problem by moving perf_event_mmap() hook to mprotect_fixup(). Note: there's another successful return path from mprotect_fixup() if old flags equal to new flags. We don't, however, need to call perf_event_mmap() there because 'perf' already knows the VMA is executable.

Commit 13cfb733 made cifs_ioctl use the tlink attached to the cifsFileInfo for a filp. This ignores the case of an open directory however, which in CIFS can have a NULL private_data until a readdir is done on it. This patch re-adds the NULL pointer checks that were removed in commit 50ae28f0 and moves the setting of tcon and "caps" variables lower. Long term, a better fix would be to establish a f_op->open routine for directories that populates that field at open time, but that requires some other changes to how readdir calls are handled.

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: Mathias Burén <mathias.buren@gmail.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: jiayingz@google.com

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.
