Hello, This patch series add two tests to verify SEEK_DATA/SEEK_HOLE feature works fine on supported file systems(Btrfs/OCFS2) and XFS which is in progress. V2 changes in seek_sanity_tester: * change test index number from 276 to 279 since I observed that 276~278 have already been used by other tests. v2 changes in seek_copy_tester: * change test index number to 280 accordingly. * s/do_pwrite/full_pwrite/ * add more debug info when writing ZERO byte to dest file. * fix a bug at create_data_and_holes() to avoid write more bytes exceeding total file size, thank Mark. :) * mark all function as static, maybe it's better to consolidate some common functions at sanity check and copy tester to a lib file in future. Thanks, -Jeff _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
