.SH NAME
ntfs_sync_mft_mirror \- synchronize an mft record to the mft mirror
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
int ntfs_sync_mft_mirror  (ntfs_volume * \fIvol\fB, const unsigned long \fImft_no\fB, MFT_RECORD * \fIm\fB, int \fIsync\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIvol\fB\fR
ntfs volume on which the mft record to synchronize resides
.TP
\fB\fImft_no\fB\fR
mft record number of mft record to synchronize
.TP
\fB\fIm\fB\fR
mapped, mst protected (extent) mft record to synchronize
.TP
\fB\fIsync\fB\fR
if true, wait for i/o completion
.SH "DESCRIPTION"
.PP
Write the mapped, mst protected (extent) mft record \fIm\fR with mft record
number \fImft_no\fR to the mft mirror (\fB$MFTMirr\fR) of the ntfs volume \fIvol\fR\&.
.PP
On success return 0.  On error return -errno and set the volume errors flag
in the ntfs volume \fIvol\fR\&.
.SH "NOTE"
.PP
We always perform synchronous i/o and ignore the \fIsync\fR parameter.
.SH "TODO"
.PP
If \fIsync\fR is false, want to do truly asynchronous i/o, i.e. just
schedule i/o via ->writepage or do it via kntfsd or whatever.
