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.
