VFS_SYNC - flush unwritten data
VFS_SYNC(struct mount *mp, int waitfor);
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
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.
fsync(2), sync(2), VFS(9), vnode(9), VOP_FSYNC(9)
