.TH "IDE_UNREGISTER" "9" "09 October 2005" "" ""

.SH NAME
ide_unregister \- free an ide interface
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
void ide_unregister  (unsigned int \fIindex\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIindex\fB\fR
index of interface (will change soon to a pointer)
.SH "DESCRIPTION"
.PP
Perform the final unregister of an IDE interface. At the moment
we don't refcount interfaces so this will also get split up.
.SH "LOCKING"
.PP
The caller must not hold the IDE locks
The drive present/vanishing is not yet properly locked
Take care with the callbacks. These have been split to avoid
deadlocking the IDE layer. The shutdown callback is called
before we take the lock and free resources. It is up to the
caller to be sure there is no pending I/O here, and that
the interfce will not be reopened (present/vanishing locking
isnt yet done btw). After we commit to the final kill we
call the cleanup callback with the ide locks held.
.PP
Unregister restores the hwif structures to the default state.
This is raving bonkers.
