These patches add missing feature descriptions and command arguments to
man pages and usage texts. They also fix some minor typos.
I'm just getting familiar with ext4, and this is the first patch series
I've sent to a mailing list, so I expect there to be issues. Please let
me know of any.
The patches are based off of the master branch of e2fsprogs. Should I be
working from a different branch? Also, I did not update any of the
localization files. Do I need to worry about handling that?
Thanks,
Tyson
Tyson Nottingham (5):
Add missing features and mount options to ext4 man page.
Add missing information to e2fsck man pages and usage text.
Add missing information to debugfs man pages and usage texts.
Add missing information to various man pages and usage texts.
Fix minor typos in libext2fs documentation.

Thanks so much for working on the e2fsprogs documentation! It is an
often an underappreciated work, and I'm glad to have someone working
to improve the documentation.

The maint branch corresponds to the 1.43.x release series, and the
master and next branches present what will (soon) become the 1.44(.x)
release. There will be at least one more 1.43.x release before I
release 1.44, so it's not that of an issue.
I can handle trying to apply these patches to the maint branch,
pulling out the feature improvements that only appear in the master
branch and applying that in a separate patch for the master branch.
But in the future, it would be preferable for bug fixes and doc fixes
to be done against the maint branch (if applicable). The master/next
branch will get fixes via git merges.
Cheers,
