Thanks, all fixed, although I think that the comma on the last
one is optional. New patch is below, although what I would
really prefer to see is this:
- Drop the "ext3dev" name. Use "ext4dev" temporarily, then
switch to "ext4".
From: Randy Dunlap <[email protected]>
Clean up help text and module names in ext4 & jbd2 Kconfig entries.
Add "depends on EXPERIMENTAL".
