sys/kern vfs_mount.c
sys/sys vnode.h
sys/ufs/ffs ffs_softdep.c
Log:
Yield the cpu in the kernel while iterating the list of the
vnodes belonging to the mountpoint. Also, yield when in the
softdep_process_worklist() even when we are not going to sleep due to
buffer drain.
It is believed that the ULE fixed the problem [1], but the yielding
seems to be needed at least for the 4BSD case.
Discussed: on stable@, with bde
