* Btrfs: sysfs: move super_kobj and device_dir_kobj from fs_info to ↵Anand Jain2015-05-274-43/+56
| | | | | | | | | | | | | | | | | | | | | | | | | btrfs_fs_devices This patch will provide a framework and help to create attributes from the structure btrfs_fs_devices which are available even before fs_info is created. So by moving the parent kobject super_kobj from fs_info to btrfs_fs_devices, it will help to create attributes from the btrfs_fs_devices as well. Patches on top of this patch now will be able to create the sys/fs/btrfs/fsid kobject and attributes from btrfs_fs_devices when devices are scanned and registered to the kernel. Just to note, this does not change any of the existing btrfs sysfs external kobject names and its attributes and not even the life cycle of them. Changes are internal only. And to ensure the same, this path has been tested with various device operations and, checking and comparing the sysfs kobjects and attributes with sysfs kobject and attributes with out this patch, and they remain same.

And when a ktime helper was changed to utilize ktime_divns, it caused a regression on some IR blasters. See the following bugzilla for details: https://bugzilla.redhat.com/show_bug.cgi?id=1200353 This patch fixes the problem in ktime_divns by checking and preserving the sign bit, and then reapplying it if appropriate after the division, it also changes the return type to a s64 to make it more obvious this is expected. Nicolas also pointed out that negative dividers would cause infinite loops on 32bit systems, negative dividers is unlikely for users of this function, but out of caution this patch adds checks for negative dividers for both 32-bit (BUG_ON) and 64-bit(WARN_ON) versions to make sure no such use cases creep in.

In retrospect it's pretty obvious that r_req_lru_item item in the case of lingering requests can be used not only for notarget, but also for unsent linkage due to how tightly actual map and enqueue operations are coupled in __map_request(). The assertion that was being silenced is taken care of in the previous ("libceph: request a new osdmap if lingering request maps to no osd") commit: by always kicking homeless lingering requests we ensure that none of them ends up on the notarget list outside of the critical section guarded by request_mutex.

First, if there are any homeless lingering requests, we now request a new osdmap even if the osdmap that is being processed brought no changes, i.e. if a given lingering request turned homeless in one of the previous epochs and remained homeless in the current epoch. Not doing so leaves us with a stale osdmap and as a result we may miss our window for reestablishing the watch and lose notifies. MON=1 OSD=1: # cat linger-needmap.sh #!/bin/bash rbd create --size 1 test DEV=$(rbd map test) ceph osd out 0 rbd map dne/dne # obtain a new osdmap as a side effect (!) sleep 1 ceph osd in 0 rbd resize --size 2 test # rbd info test | grep size -> 2M # blockdev --getsize $DEV -> 1M N.B.: Not obtaining a new osdmap in between "osd out" and "osd in" above is enough to make it miss that resize notify, but that is a bug^Wlimitation of ceph watch/notify v1. Second, homeless lingering requests are now kicked just like those lingering requests whose mapping has changed. This is mainly to recognize that a homeless lingering request makes no sense and to preserve the invariant that a registered lingering request is not sitting on any of r_req_lru_item lists. This spares us a WARN_ON, which commit ba9d114ec557 ("libceph: clear r_req_lru_item in __unregister_linger_request()") tried to fix the _wrong_ way.

This fixed failures when there was no space on the drive to allocate a new chunk, but the metadata reserves were sufficient to continue the conversion. But this ended up causing a regression when the drive had plenty of space to allocate new chunks, mostly because reduce_alloc_profile isn't using the new raid profile. Fixing btrfs_reduce_alloc_profile is a bigger patch. For now, do a partial revert of 2f0810880, and don't error out if we hit ENOSPC.

The fix is simple - we just have to clear 'ret' after we are done processing the results of find_parent_nodes(). It wasn't clear to me at first what was happening with return values in btrfs_check_shared() and find_parent_nodes() - thanks to Josef for the help on irc.

In case of Exynos DRM, There was a special case which decides pixel format of a given buffer according to planer types, which is NV12M and NV12. However, NV12M doesn't exist in drm fourcc so it removes exynos_drm_format_num_buffers() specific to Exynos DRM and use a generic function, drm_format_num_planes() instead. - Allow mixer driver to support NV21 format for Video processor. This format was already supported but we just missed DRM_FORMAT_NV21 case so this patch considers the case so that Mixer driver can handle it correctly. - Add regression fix and some code cleanups. * 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: dp: Lower level of EDID read success message drm/exynos: cleanup exynos_drm_plane drm/exynos: 'win' is always unsigned drm/exynos: mixer: don't dump registers under spinlock drm/exynos: Consolidate return statements in fimd_bind() drm/exynos: Constify exynos_drm_crtc_ops drm/exynos: Fix build breakage on !DRM_EXYNOS_FIMD drm/exynos: mixer: Constify platform_device_id drm/exynos: mixer: cleanup pixelformat handling drm/exynos: mixer: also allow NV21 for the video processor drm/exynos: mixer: remove buffer count handling in vp_video_buffer() drm/exynos: plane: honor buffer offset for dma_addr drm/exynos: fb: use drm_format_num_planes to get buffer count
