help
Fire the lock:contended_release tracepoint when a contended queued
spinlock is released, so it is possible to attribute a contended
spinlock to its holder.
Architectures that can patch the unlock site do this at no cost and
do not need this option.
Everywhere else the check is compiled into queued_spin_unlock() and
a small cost is paid on every unlock even when the tracepoint is
disabled: a static-branch NOP and possibly a few more instructions
to manage a stack frame.
Sleeping locks fire lock:contended_release regardless of this option.
If unsure, say N.
