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.
