Hi James, After merging the block tree, today's linux-next build (powerpc ppc44x_defconfig) produced this warning: block/blk-lib.c: In function 'blkdev_issue_zeroout': block/blk-lib.c:190: warning: comparison of distinct pointer types lacks a cast Introduced by commit 3f14d792f9a8fede64ce918dbb517f934497a4f8 ("blkdev: add blkdev_issue_zeroout helper function"). -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
