Subject: [PATCH] e2fsprogs: obsolete hurd and masix support
Theodore,
Here is the patch to remove obsoleted code piece by piece.
This patch remove hurd and masix support, including union of inode and related source code.
I find there (likely) are some hurd related code in lib/ext2fs/ismounted.c. But I am not sure
whether the "#ifndef __GNU__" is hurd specific only. What is your comment ?
This time, I use MIME/PGP in my signature, and tested by sending the patch to another account. Hope
the format is ok this time :-)
