1) Lockdep thinks all nouveau subdevs belong to the same class and can be locked in arbitrary order, which is not true (at least in general case). Tell it to distinguish subdevs by (o)class type. 2) DRM client can be locked under user client lock - tell lockdep to put DRM client lock in a separate class. Reported-by:

This fixes up commit e8e89622 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Dec 18 22:25:11 2012 +0100 drm/ttm: fix fence locking in ttm_buffer_object_transfer which leaves behind a might_sleep in atomic context, since the fence_lock spinlock is held over a kmalloc(GFP_KERNEL) call. The fix is to revert the above commit and only take the lock where we need it, around the call to ->sync_obj_ref. v2: Fixup things noticed by Maarten Lankhorst: - Brown paper bag locking bug. - No need for kzalloc if we clear the entire thing on the next line. - check for bo->sync_obj (totally unlikely race, but still someone else could have snuck in) and clear fbo->sync_obj if it's cleared already.

The RTC control register should be enabled in the process of initializing. Without this patch, I failed to enable RTC in Hisilicon Hi3620 SoC. The register mapping section in RTC is always read as zero. So I doubt that ST guys may already enable this register in bootloader. So they won't meet this issue. Signed-off-by:

The seccomp filters are currently built for the build host, not for the machine that they are going to run on, but they are also built for with the -m32 flag if the kernel is built for a 32 bit machine, both of which seems rather odd. It broke allyesconfig on my machine, which is x86-64, but building for 32 bit ARM, with this error message: In file included from /usr/include/stdio.h:28:0, from samples/seccomp/bpf-fancy.c:15: /usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directory because there are no 32 bit libc headers installed on this machine. We should really be building all the samples for the target machine rather than the build host, but since the infrastructure for that appears to be missing right now, let's be a little bit smarter and not pass the '-m32' flag to the HOSTCC when cross- compiling.

The macro for_each_memcg_cache_index contains a silly yet potentially deadly mistake. Although the macro parameter is _idx, the loop tests are done over i, not _idx. This hasn't generated any problems so far, because all users use i as a loop index. However, while playing with an extension of the code I ended using another loop index and the compiler was quick to complain. Unfortunately, this is not the kind of thing that testing reveals =( Signed-off-by:

There exists a situation when GC can work in background alone without any other filesystem activity during significant time. The nilfs_clean_segments() method calls nilfs_segctor_construct() that updates superblocks in the case of NILFS_SC_SUPER_ROOT and THE_NILFS_DISCONTINUED flags are set. But when GC is working alone the nilfs_clean_segments() is called with unset THE_NILFS_DISCONTINUED flag. As a result, the update of superblocks doesn't occurred all this time and in the case of SPOR superblocks keep very old values of last super root placement. SYMPTOMS: Trying to mount a NILFS2 volume after SPOR in such environment ends with very long mounting time (it can achieve about several hours in some cases). REPRODUCING PATH: 1. It needs to use external USB HDD, disable automount and doesn't make any additional filesystem activity on the NILFS2 volume. 2. Generate temporary file with size about 100 - 500 GB (for example, dd if=/dev/zero of=<file_name> bs=1073741824 count=200). The size of file defines duration of GC working. 3. Then it needs to delete file. 4. Start GC manually by means of command "nilfs-clean -p 0". When you start GC by means of such way then, at the end, superblocks is updated by once. So, for simulation of SPOR, it needs to wait sometime (15 - 40 minutes) and simply switch off USB HDD manually. 5. Switch on USB HDD again and try to mount NILFS2 volume. As a result, NILFS2 volume will mount during very long time. REPRODUCIBILITY: 100% FIX: This patch adds checking that superblocks need to update and set THE_NILFS_DISCONTINUED flag before nilfs_clean_segments() call. Reported-by:

When we have group with mixed events (hw/sw) we want to end up with group leader being in hw context. So if group leader is initialy sw event, we move all the events under hw context. The move is done for each event by removing it from its context and adding it back into proper one. As a part of the removal the event is automatically disabled, which is not what we want at this stage of creating groups. The fix is to initialize event state after removal from sw context. This fix resulted from the following discussion: http://thread.gmane.org/gmane.linux.kernel.perf.user/1144Reported-by:

Pull scsi target fixes from Nicholas Bellinger: "Here's the current set of v3.8-rc fixes in the target-pending.git queue. Apologies in advance for these missing the -rc6 release, and having to be destined for -rc7 code. The majority of these patches are regression bugfixes specific to v3.8-rc code changes, namely the zero-length CDB handling breakage after the sense_reason_t conversion, and preventing configfs port linking for unconfigured devices after the recent struct se_subsystem_dev removal. These is also one (the divide by zero bug for unconfigured devices) that is CC'ed to stable." * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target: Fix divide by zero bug in fabric_max_sectors for unconfigured devices target: Fix regression allowing unconfigured devices to fabric port link tcm_vhost: fix pr_err on early kick target: Fix zero-length READ_CAPACITY_16 regression target: Fix zero-length MODE_SENSE regression target: Fix zero-length INQUIRY additional sense code regression
