35 .Nd flush filesystem buffers for a file
40 .Fn VOP_FSYNC "struct vnode *vp" "struct ucred *cred" "int waitfor" "struct proc *p"
42 This call flushes any dirty filesystem buffers for the file.
43 It is used to implement the
50 .Bl -tag -width waitfor
54 the caller's credentials
56 whether the function should wait for I/O to complete
67 and specifies whether or not the function should wait for the writes
