e2fsprogs: add supported file attributes to ext4.5 manpage
|
||
|
|
|
||
|
|
The chattr(1) manpage now refers users to filesystem-specific
|
||
|
|
manpages for details on supported attributes, so add those to
|
||
|
|
ext4.5.
|
||
|
|
|
||
|
|
I've left out oddities like being able to set the compressed
|
||
|
|
or no-tail-packing flags, or setting data journaling on ext2.
|
||
|
|
|
||
|
|
That behavior seems like a bug, not a feature.
