Real world year equals the value in vrtc YEAR register plus an offset. We used 1960 as the offset to make leap year consistent, but for a device's first use, its YEAR register is 0 and the system year will be parsed as 1960 which is not a valid UNIX time and will cause many applications to fail mysteriously. So we use 1972 instead to fix this issue. Updated patch which adds a sanity check suggested by Mathias This isn't a change in behaviour for systems, because 1972 is the one we actually use. It's the old version in upstream which is out of sync with all devices. Signed-off-by:

during the review of the fix for locks problems in drm_wait_vblank, a couple of false concerns were raised about how the drm_vblank_get and drm_vblank_put are used in this function; it turned out that the code is correct and that it cannot be simplified add a few comments to explain non-obvious flows in the code, to prevent "false alarms" in the future v2: incorporate comments received from Daniel Vetter Signed-off-by:

drm_wait_vblank must be DRM_UNLOCKED because otherwise it will grab the drm_global_mutex and then go to sleep until the vblank event it is waiting for. That can wreck havoc in the windowing system because if one process issues this ioctl, it will block all other processes for the duration of all vblanks between the current and the one it is waiting for. In some cases it can block the entire windowing system. v2: incorporate comments received from Daniel Vetter and Michel Daenzer. v3/v4: after a lengty discussion with Daniel Vetter, it was concluded that the only thing not yet protected with locks and atomic ops is the write to dev->last_vblank_wait. It's only used in a debug file in proc, and the current code already employs no correct locking: the proc file only takes dev->struct_mutex, whereas drm_wait_vblank implicitly took the drm_global_mutex. Given all this, it's not worth bothering to try to fix the locks at this time. Signed-off-by: -

Nouveau, when configured with debugfs, creates debugfs files for every channel, so structure holding list of files needs to be protected from simultaneous changes by multiple threads. Without this patch it's possible to hit kernel oops in drm_debugfs_remove_files just by running a couple of xterms with looped glxinfo. Signed-off-by:

This was only the case if the GPU reset was triggered from the CS ioctl, otherwise other processes could happily enter the CS ioctl and wreak havoc during the GPU reset. This is a little complicated because the GPU reset can be triggered from the CS ioctl, in which case we're already holding the mutex, or from other call paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't allow recursive locking or finding out the mutex owner, so we need to handle this with helper functions which allow recursive locking from the same process.

People have been running into a warning when loading space cache because the page is already mapped when trying to read in a bitmap. The way we read in entries and pages is kind of convoluted, so fix it so that io_ctl_read_entry maps the entries if it needs to, and if it hits the end of the page it simply unmaps the page. That way we can unconditionally unmap the io_ctl before reading in the bitmap and we should stop hitting these warnings. Thanks, Signed-off-by:

If the root node of a fs/file tree is in the block group that is being relocated, but the others are not in the other block groups. when we create a snapshot for this tree between the relocation tree creation ends and ->create_reloc_tree is set to 0, Btrfs will create some backref nodes that are the lowest nodes of the backrefs cache. But we forget to add them into ->leaves list of the backref cache and deal with them, and at last, they will triggered BUG_ON(). kernel BUG at fs/btrfs/relocation.c:239! This patch fixes it by adding them into ->leaves list of backref cache. Signed-off-by:

When we did stress test for the space relocation, the deadlock happened. By debugging, We found it was caused by the carelessness that we forgot to unlock the read lock of the extent buffers in btrfs_orphan_cleanup() before we end the transaction handle, so the transaction commit task waited the task, which called btrfs_orphan_cleanup(), to unlock the extent buffer, but that task waited the commit task to end the transaction commit, and the deadlock happened. Fix it. Signed-ff-by:
