+Subject: Bluetooth: btrtl: Additional Realtek 8822CE Bluetooth devices
+
+From: Jian-Hong Pan <jian-hong@endlessm.com>
+
+[ Upstream commit 6d0762b19c5963ff9e178e8af3626532ee04d93d ]
+
+The ASUS X412FA laptop contains a Realtek RTL8822CE device with an
+associated BT chip using a USB ID of 04ca:4005. This ID is added to the
+driver.
+
+The /sys/kernel/debug/usb/devices portion for this device is:

+Subject: drm: Flush output polling on shutdown
+
+From: Chris Wilson <chris@chris-wilson.co.uk>
+
+[ Upstream commit 3b295cb1a411d9c82bbfaa66bc17a8508716ed07 ]
+
+We need to mark the output polling as disabled to prevent concurrent
+irqs from queuing new work as shutdown the probe -- causing that work to
+execute after we have freed the structs:

+ F2FS-fs (sdb): Bitmap was wrongly set, blk:4608
+ kernel BUG at fs/f2fs/segment.c:2133!
+ RIP: 0010:update_sit_entry+0x35d/0x3e0
+ Call Trace:

+ entry_SYSCALL_64_after_hwframe+0x44/0xa9
+
+The testcase fails because that, in fuzzed image, current segment was
+allocated with LFS type, its .next_blkoff should point to an unused
+block address, but actually, its bitmap shows it's not. So during
+allocation, f2fs crash when setting bitmap.
+
+Introducing sanity_check_curseg() to check such inconsistence of
+current in-used segment.

+Subject: xfs: don't crash on null attr fork xfs_bmapi_read
+
+From: Darrick J. Wong <darrick.wong@oracle.com>
+
+[ Upstream commit 8612de3f7ba6e900465e340516b8313806d27b2d ]
+
+Zorro Lang reported a crash in generic/475 if we try to inactivate a
+corrupt inode with a NULL attr fork (stack trace shortened somewhat):

+
+The "obvious" cause is that the attr ifork is null despite the inode
+claiming an attr fork having at least one extent, but it's not so
+obvious why we ended up with an inode in that state.
