vinvalbuf - flush and invalidate all buffers associated with
vinvalbuf(struct vnode *vp, int flags, struct ucred *cred,
struct proc *p, int slpflag, int slptimeo);
The vinvalbuf() function invalidates all of the buffers associated with
the given vnode. This includes buffers on the clean list
and the dirty
list. If the V_SAVE flag is specified then the buffers on
the dirty list
are synced prior to being released. If the V_SAVEMETA flag
is set, indirect
blocks will not be flushed.
Its arguments are:
vp A pointer to the vnode whose buffers will be
flags The supported flags are V_SAVE and V_SAVEMETA.
that dirty buffers should be synced
with the disk.
V_SAVEMETA indicates that indirect blocks
should not be
cred The user credentials that are used to
if V_SAVE is set.
p The process responsible for this call.
slpflag The slp flag that will be used in the priority
sleeps in the function.
slptimeo The timeout for any sleeps in the function.
The vnode is assumed to be locked prior to the call and remains locked
A value of 0 is returned on success.
vn_lock(devvp, LK_EXCLUSIVE | LK_RETRY, p);
error = vinvalbuf(devvp, V_SAVE, cred, p, 0, 0);
VOP_UNLOCK(devvp, 0, p);
[ENOSPC] The file system is full. (With V_SAVE)
[EDQUOT] Disc quota exceeded. (With V_SAVE)
Sleep operation timed out. (See slptimeo)
[ERESTART] A signal needs to be delivered and the system
be restarted. (With PCATCH set in slpflag)
[EINTR] The system has been interrupted by a signal.
