Name
try_wait_for_completion —
try to decrement a completion without blocking
Synopsis
bool try_wait_for_completion ( | struct completion * x); |
Returns
0 if a decrement cannot be done without blocking
1 if a decrement succeeded.
If a completion is being used as a counting completion,
attempt to decrement the counter without blocking. This
enables us to avoid waiting if the resource the completion
is protecting is not available.
