Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: xfs: bail out on bitmap errors in xrep_agfl_fill LOLLM also points out that the xagb_bitmap_set call in xrep_agfl_fill can fail, but we don't check the result of xagb_bitmap_walk, so we silently drop the error and proceed with inconsistent incore data. That shouldn't be allowed.
