Nope, that won't work, since we need _require_scratch_nocheck for one of the tests. OK, here's V3 of the patch. WDYT? - Ted commit b9d9da8b901acc5b6cb5da7149b7e8ce986e436e Author: Theodore Ts'o <tytso@xxxxxxx> Date: Sat Nov 11 23:28:51 2017 -0500 common: rework _require_ext4_mkfs_feature In all of the places where we need check to see if mkfs.ext4 can support a set of file system features, we also should be checking to see if the kernel can support those file system features. So rename _require_ext4_mkfs_feature to _require_ext4_feature, and actually format the file system in $SCRATCH. To avoid running mkfs twice in most tests, we will teach the tests to assume that _require_ext4_feature actually leaves $SCRATCH formatted with a file system with those features. Also allow ext4/306 to run on systems where mke2fs doesn't support the "64bit" option.
