| H A D | vfs_cluster.c | diff 86089 Mon Nov 05 16:48:54 MST 2001 dillon Implement IO_NOWDRAIN and B_NOWDRAIN - prevents the buffer cache from blocking in wdrain during a write. This flag needs to be used in devices whos strategy routines turn-around and issue another high level I/O, such as when MD turns around and issues a VOP_WRITE to vnode backing store, in order to avoid deadlocking the dirty buffer draining code. Remove a vprintf() warning from MD when the backing vnode is found to be in-use. The syncer of buf_daemon could be flushing the backing vnode at the time of an MD operation so the warning is not correct. MFC after: 1 week |
