gcc bug again? Corresponding preprocessed source when XFS realtime allocator
is off:
static int xfs_bmap_rtalloc(xfs_bmalloca_t *ap)
{
...
xfs_rtblock_t rtx;
...
if (ap->eof && ap->off == 0) {
===> error = (251); <===
if (error)
return error;
ap->rval = rtx * mp->m_sb.sb_rextsize;
} else {
ap->rval = 0;
}
This is the only place where rtx is "used".
When realtime allocator is on, xfs_rtpick_extent() is real function
either a) returning error and leaving garbage in "rtx", or b)
initializing "rtx" and returning 0.
