48703fedf1 No longer need to set B_ASYNC flag since BUF_KERNPROC now 
unconditionally sets the identity of the buffer.
 1999-06-29 15:57:40 +00:00

ddebd8794d Hopefully fix the remaining glitches with the BUF_*() changes. This should 
(really this time) fix pageout to swap and a couple of clustering cases.

This simplifies BUF_KERNPROC() so that it unconditionally reassigns the
lock owner rather than testing B_ASYNC and having the caller decide when
to do the reassign.  At present this is required because some places use
B_CALL/b_iodone to free the buffers without B_ASYNC being set.  Also,
vfs_cluster.c explicitly calls BUF_KERNPROC() when attaching the buffers
rather than the parent walking the cluster_head tailq.

72283ee95d Fix a bug that was almost certainly making breadn() fail. BUF_KERNPROC() 
was being called on the wrong bp - it should be called on the one that's
just about to be fed to VOP_STRATEGY().

Zap symbols.raw and glue to make symbols.* - it's not used on the ELF-only

in-kernel linker symbol lookup.

33638e9384 When requesting an exclusive lock with LK_NOWAIT, do not panic 
if LK_RECURSIVE is not set, as we will simply return that the
lock is busy and not actually deadlock. This allows processes
to use polling locks against buffers that they may already
hold exclusively locked.

Change etc/defaults/rc.conf so as to encourage wrapping on new systems.
