Oops, I noticed one slight typo in the -v4 patch; here's a revised version.
commit 11bf2e5d9cec9bf8ca53cffbb14383d0b21583fe
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.
