| 866e4ed | Christoph Hellwig | 27 August 2011, 05:57:44 UTC | xfs: fix xfs_mark_inode_dirty during umount During umount we do not add a dirty inode to the lru and wait for it to become clean first, but force writeback of data and metadata with I_WILL_FREE set. Currently there is no way for XFS to detect that the inode has been redirtied for metadata operations, as we skip the mark_inode_dirty call during teardown. Fix this by setting i_update_core nanually in that case, so that the inode gets flushed during inode reclaim. Alternatively we could enable calling mark_inode_dirty for inodes in I_WILL_FREE state, and let the VFS dirty tracking handle this. I decided against this as we will get better I/O patterns from reclaim compared to the synchronous writeout in write_inode_now, and always marking the inode dirty in some way from xfs_mark_inode_dirty is a better safetly net in either case.

| 8c0bec2 | Jiaying Zhang | 31 August 2011, 15:50:51 UTC | ext4: remove i_mutex lock in ext4_evict_inode to fix lockdep complaining The i_mutex lock and flush_completed_IO() added by commit 2581fdc810 in ext4_evict_inode() causes lockdep complaining about potential deadlock in several places. In most/all of these LOCKDEP complaints it looks like it's a false positive, since many of the potential circular locking cases can't take place by the time the ext4_evict_inode() is called; but since at the very least it may mask real problems, we need to address this. This change removes the flush_completed_IO() and i_mutex lock in ext4_evict_inode(). Instead, we take a different approach to resolve the software lockup that commit 2581fdc810 intends to fix. Rather than having ext4-dio-unwritten thread wait for grabing the i_mutex lock of an inode, we use mutex_trylock() instead, and simply requeue the work item if we fail to grab the inode's i_mutex lock. This should speed up work queue processing in general and also prevents the following deadlock scenario: During page fault, shrink_icache_memory is called that in turn evicts another inode B. Inode B has some pending io_end work so it calls ext4_ioend_wait() that waits for inode B's i_ioend_count to become zero. However, inode B's ioend work was queued behind some of inode A's ioend work on the same cpu's ext4-dio-unwritten workqueue. As the ext4-dio-unwritten thread on that cpu is processing inode A's ioend work, it tries to grab inode A's i_mutex lock. Since the i_mutex lock of inode A is still hold before the page fault happened, we enter a deadlock.

The IPI interrupt is therefore changed to IRQ 13, which is the highest normally handled interrupt. This IRQ is also used for SBUS interrupts, however there is nothing in the IPI/SBUS interrupt handlers that indicate that they will not handle sharing the interrupt.

| a8d757e | Stephane Eranian | 25 August 2011, 13:58:03 UTC | perf events: Fix slow and broken cgroup context switch code The current cgroup context switch code was incorrect leading to bogus counts. Furthermore, as soon as there was an active cgroup event on a CPU, the context switch cost on that CPU would increase by a significant amount as demonstrated by a simple ping/pong example: $ ./pong Both processes pinned to CPU1, running for 10s 10684.51 ctxsw/s Now start a cgroup perf stat: $ perf stat -e cycles,cycles -A -a -G test -C 1 -- sleep 100 $ ./pong Both processes pinned to CPU1, running for 10s 6674.61 ctxsw/s That's a 37% penalty. Note that pong is not even in the monitored cgroup. The results shown by perf stat are bogus: $ perf stat -e cycles,cycles -A -a -G test -C 1 -- sleep 100 Performance counter stats for 'sleep 100': CPU1 <not counted> cycles test CPU1 16,984,189,138 cycles # 0.000 GHz The second 'cycles' event should report a count @ CPU clock (here 2.4GHz) as it is counting across all cgroups. The patch below fixes the bogus accounting and bypasses any cgroup switches in case the outgoing and incoming tasks are in the same cgroup. With this patch the same test now yields: $ ./pong Both processes pinned to CPU1, running for 10s 10775.30 ctxsw/s Start perf stat with cgroup: $ perf stat -e cycles,cycles -A -a -G test -C 1 -- sleep 10 Run pong outside the cgroup: $ /pong Both processes pinned to CPU1, running for 10s 10687.80 ctxsw/s The penalty is now less than 2%. And the results for perf stat are correct: $ perf stat -e cycles,cycles -A -a -G test -C 1 -- sleep 10 Performance counter stats for 'sleep 10': CPU1 <not counted> cycles test # 0.000 GHz CPU1 23,933,981,448 cycles # 0.000 GHz Now perf stat reports the correct counts for for the non cgroup event. If we run pong inside the cgroup, then we also get the correct counts: $ perf stat -e cycles,cycles -A -a -G test -C 1 -- sleep 10 Performance counter stats for 'sleep 10': CPU1 22,297,726,205 cycles test # 0.000 GHz CPU1 23,933,981,448 cycles # 0.000 GHz 10.001457237 seconds time elapsed Signed-off-by: Stephane Eranian <eranian@google.com> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/20110825135803.GA4697@quad Signed-off-by: Ingo Molnar <mingo@elte.hu> | 29 August 2011, 10:28:33 UTC |

| 4861da4 | Magnus Damm | 10 August 2011, 05:45:30 UTC | ARM: mach-shmobile: Remove 3DG/SGX from sh7372 INTCS This patch removes support for the SGX interrupt source in the sh7372 INTCS controller. The SGX hardware block included in sh7372 is already hooked up to the ARM Cortex-A8 core using the INTCA controller, so SGX users are encouraged to make use of that interrupt source instead. Removing support for the SGX interrupt source in INTCS simplifies the sh7372 power management code by allowing us to assume that only INTCA needs to be powered on to operate the SGX hardware. If the INTCS interrupt source would be kept then the kernel would be forced to deal with additional dependencies that does not follow the regular power domain hiearachy. With this patch in place we can safely power down INTCS while the SGX is operating.

There is no software code, nor needs to get/set real CTS signal. But, when turning CRTSCTS on through termios, uart_set_termios() in serial_core.c checks CTS, and stops TX if it is inactive at the moment. Because sci_get_mctrl() returns a fixed value DTR|RTS|DSR but CTS, the sequence open -> set CRTSCTS -> write hit the case and stop working, no more outputs.

This field can accidentally be left initialized, which is why we currently memset buffers returned to userland in rtc_read_time. There is a case however where the field can return garbage from the stack though when using the RTC_ALM_READ ioctl on the rtc device. This ioctl invokes rtc_read_alarm, which is careful to memset the rtc_wkalrm buffer that is copied to userland, but it then uses a struct copy to assign to alarm->time given the return value from rtc_ktime_to_tm(). rtc_ktime_to_tm() is implemented by calling rtc_time_to_tm using a derivative seconds counds from ktime, but rtc_time_to_tm does not assign a value to ->tm_isdst. This results in garbage from rtc_ktime_to_tm()'s frame ending up being copied out to userland as part of the returned rtc_wkalrm. Fix this by initializing rtc_time->tm_isdst to 0 in rtc_time_to_tm.
