| H A D | lockmgr.h | diff 177687 Fri Mar 28 10:30:12 MDT 2008 attilio b_waiters cannot be adequately protected by the interlock because it is dropped after the call to lockmgr() so just revert this approach using something similar to the precedent one: BUF_LOCKWAITERS() just checks if there are waiters (not the actual number of them) and it is based on newly introduced lockmgr_waiters() which returns if the lockmgr has waiters or not. The name has been choosen differently by old lockwaiters() in order to not confuse them. KPI results enriched by this commit so __FreeBSD_version bumping and manpage update will be happening soon. 'struct buf' also changes, so kernel ABI is disturbed. Bug found by: jeff Approved by: jeff, kib |
