Subject: debugfs: fix various minor bogosity
X-Git-Tag: v1.42.9~84
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;ds=sidebyside;h=50295a3f9e40894316301bebcc7247e9ec85f506;p=thirdparty%2Fe2fsprogs.git

debugfs: fix various minor bogosity

We should really use the ext2fs memory allocator functions in
copy_file(), and we really should return a value if there's allocation
problems.

Also fix up a minor bogosity in an error message.
