NAME
VFS_SYNC —
flush unwritten data
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
#include <sys/vnode.h>
int
VFS_SYNC(struct
mount *mp, int
waitfor);
DESCRIPTION
TheVFS_SYNC() macro writes out all unwritten data in
the file system mounted as mp.
The arguments it expects are:
- mp
- The file system.
- waitfor
- Whether the function should wait for I/O to complete. Possible values are:
MNT_WAIT- synchronously wait for I/O to complete
MNT_NOWAIT- start all I/O, but do not wait for it
MNT_LAZY- push data not written by file system syncer
The VFS_SYNC() macro calls the
vfs_sync method of the file system, which normally
calls
VOP_FSYNC(9)
for all the vnodes in the file system.
