sys/ufs/ffs : ffs_softdep.c
Log message:
Call process_worklist_item with LK_NOWAIT to skip locked vnodes from
within softdep_process_worklist. When this is called from the syncer
a vnode may be legtitimately locked by someone waiting for buffers
so we need to skip anything locked. FreeBSD appears to have a similar
change. This avoids a deadlock where the syncer ends up waiting for
the inode lock that his held by someone waiting for buffer space.
