xfs: eliminate some newly-reported gcc warnings (9c169915) · Commits · 戴 / test

Ionut Gabriel Popescu <poyo_vl@yahoo.com> submitted a simple change to eliminate some "may be used uninitialized" warnings when building XFS. The reported condition seems to be something that GCC did not used to recognize or report. The warnings were produced by: gcc version 4.5.0 20100604 [gcc-4_5-branch revision 160292] (SUSE Linux) Signed-off-by:
