VFS_SYNC
VFS_SYNC(9) FreeBSD Kernel Developer's Manual VFS_SYNC(9)
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, struct ucred *cred,
struct thread *td);
DESCRIPTION
The VFS_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
cred The caller's credentials.
td The calling thread.
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.
