Jeff Roberson 2f05568aa8 - Check the XLOCK before inspecting v_data. ... - Slightly rewrite the fsync loop to be more lock friendly. We must acquire the vnode interlock before dropping the mnt lock. We must also check XLOCK to prevent vclean() races. - Use LK_INTERLOCK in the vget() in ffs_sync to further prevent vclean() races. - Use a local variable to store the results of the nvp == TAILQ_NEXT test so that we do not access the vp after we've vrele()d it. - Add an XXX comment about UFS_UPDATE() not being protected by any lock here. I suspect that it should need the VOP lock.		2003-10-05 07:16:45 +00:00

ufs	- Don't cache_purge() in ufs_reclaim. vclean() does it for us so	2003-10-05 02:45:00 +00:00
