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 fir
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.

If you have a many-core machine, and have many threads all wanting to
briefly lock a give file (udev is known to do this), you can get quite
poor performance.
When one thread releases a lock, it wakes up all other threads that
are waiting (classic thundering-herd) - one will get the lock and the

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 re
struct file lock contains an 'fl_next' pointer which
is used to point to the lock that this request is blocked
waiting for. So rename it to fl_blocker.
The fl_blocked list_head in an active lock is the head of a list of
blocked requests. In a request it is a node in that list.
