Adding reset API for UDC bus reset handler is useful for below two issues. Current disconnect API at usb_gadget_driver is also invoked at udc's bus reset handler, but the document says it is invoked when the host is disconnected. Besides, we may expect the gadget_driver to do different things for host sends bus reset and host disconnects gadget, eg, we may not want to flush dirty page for mass storage at bus reset, and want to do it at disconnection.

Laurent Pinchart authored
To handle class requests received on ep0, the driver needs to access the length and direction of the request after the setup stage. It currently stores them in a v4l2 event during the setup stage, and then copies them from the event structure to the driver internal state structure when the event is dequeued. This two-steps approach isn't necessary. Simplify the driver by storing the needed information in the driver internal state structure directly during the setup stage. Signed-off-by:

Commit 0244756e ("ufs: sb mutex merge + mutex_destroy") introduces deadlocks in ufs_new_inode() and ufs_free_inode(). Most callers of that functions acqure the mutex by themselves and ufs_{new,free}_inode() do that via lock_ufs(), i.e we have an unavoidable double lock. The patch proposes to resolve the issue by making sure that ufs_{new,free}_inode() are not called with the mutex held. Found by Linux Driver Verification project (linuxtesting.org).

Pull xfs fixes from Dave Chinner: "The fixes all address recently discovered data corruption issues. The original Direct IO issue was discovered by Chris Mason @ Facebook on a production workload which mixed buffered reads with direct reads and writes IO to the same file. The fix for that exposed other issues with page invalidation (exposed by millions of fsx operations) failing due to dirty buffers beyond EOF. Finally, the collapse_range code could also cause problems due to racing writeback changing the extent map while it was being shifted around. The commits for that problem are simple mitigation fixes that prevent the problem from occuring. A more robust fix for 3.18 that addresses the underlying problem is currently being worked on by Brian. Summary of fixes: - a direct IO read/buffered read data corruption - the associated fallout from the DIO data corruption fix - collapse range bugs that are potential data corruption issues" * tag 'xfs-for-linus-3.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: xfs: trim eofblocks before collapse range xfs: xfs_file_collapse_range is delalloc challenged xfs: don't log inode unless extent shift makes extent modifications xfs: use ranged writeback and invalidation for direct IO xfs: don't zero partial page cache pages during O_DIRECT writes xfs: don't zero partial page cache pages during O_DIRECT writes xfs: don't dirty buffers beyond EOF

The update_walltime() code works on the shadow timekeeper to make the seqcount protected region as short as possible. But that update to the shadow timekeeper does not update all timekeeper fields because it's sufficient to do that once before it becomes life. One of these fields is tkr.base_mono. That stays stale in the shadow timekeeper unless an operation happens which copies the real timekeeper to the shadow. The update function is called after the update calls to vsyscall and pvclock. While not correct, it did not cause any problems because none of the invoked update functions used base_mono. commit cbcf2dd3 (x86: kvm: Make kvm_get_time_and_clockread() nanoseconds based) changed that in the kvm pvclock update function, so the stale mono_base value got used and caused kvm-clock to malfunction. Put the update where it belongs and fix the issue. Reported-by:
