Currently, a lock can block pending requests, but all pending
requests are equal. If lots of pending requests are
mutually exclusive, this means they will all be woken up
and all but one will fail. This can hurt performance.
So we will allow pending requests to block other requests.
Only the
posix_locks_conflict() and flock_locks_conflict() both return int.
leases_conflict() returns bool.
This inconsistency will cause problems for the next patch if not
fixed.
So change posix_locks_conflict() and flock_locks_conflict() to return
bool.
Also change the locks_conflict() helper.
And
When we find an existing lock which conflicts with a request,
and the request wants to wait, we currently add the request
to a list. When the lock is removed, the whole list is woken.
This can cause the thundering-herd problem.
To reduce the problem, we make use of the (new) fact that
a pending
Now that requests can block other requests, we
need to be careful to always clean up those blocked
requests.
Any time that we wait for a request, we might have
other requests attached, and when we stop waiting,
we must clean them up.
If the lock was granted, the requests might have been
moved to
Both locks_remove_posix() and locks_remove_flock() use a
struct file_lock without calling locks_init_lock() on it.
This means the various list_heads are not initialized, which
will become a problem with a later patch.
So change them both to initialize properly. For flock locks,
this involves

- spaces at the end of lines,
- multiple blank lines,
- blank lines before EXPORT_SYMBOL,

posix_unblock_lock() is not specific to posix locks, and behaves
nearly identically to locks_delete_block() - the former returning a

So discard posix_unblock_lock() and use locks_delete_block() instead,
after giving that function an appropriate return value.

I'd like to bring up a question about multiplexing /dev/console to
all specified console= devices on the kernel command line rather than just
the last entry. In my personal experience using linux systems and also in
my experience dealing with users of various server images

The per-CPU rcu_dynticks.rcu_urgent_qs variable communicates an urgent
need for an RCU quiescent state from the force-quiescent-state processing
within the grace-period kthread to context switches and to cond_resched().
Unfortunately, such urgent needs are not

Fix kernel-doc warnings in kernel/resource.c.
The first group of warnings is caused by a "/**" kernel-doc notation
marker but the function comments are not in kernel-doc format.
Also add another error return value here.

Currently the generic SDHCI code in the Linux kernel supports the SD
standard DMA integrated into the host controller but does not have any
support for external DMA controllers implemented using dmaengine meaning
that custom code is needed for any systems that use a generic DMA
controller with
Add the HXT vendor ID to pci_ids.h and use it in quirks. As the
design of HXT SD4800 ACS feature is the same as QCOM QDF2xxx,
pci_quirk_qcom_rp_acs() is reused for SD4800 quirk.
