setting the B_REMFREE flag in the buf. This is done to prevent lock order reversals with code that must call bremfree() with a local lock held. This also reduces overhead by removing two lock operations per buf for fsync() and similar. - Check for the B_REMFREE flag in brelse() and bqrelse() after the bqlock has been acquired so that we may remove ourself from the free-list. - Provide a bremfreef() function to immediately remove a buf from a free-list for use only by NFS. This is done because the nfsclient code overloads the b_freelist queue for its own async. io queue. - Simplify the numfreebuffers accounting by removing a switch statement that executed the same code in every possible case. - getnewbuf() can encounter locked bufs on free-lists once Giant is removed. Remove a panic associated with this condition and delay asserts that inspect the buf until after it is locked. Reviewed by: phk Sponsored by: Isilon Systems, Inc. |
