Subject: [PATCH] threads: fix WAIT_SYNC_INIT with a zero count
|
|
|
|
WAIT_SYNC_INIT(sync,0); WAIT_SYNC_RELEASE(sync);
|
|
hanged because sync->signaled was initialised to true, and
|
|
there is no reason to invoke WAIT_SYNC_SIGNALED(sync) before
|
|
WAIT_SYNC_RELEASE(sync)
|
|
this commit initializes sync->signaled to true unless the count is zero.
|
|
|
|
Thanks George for the review and guidance.
