OK, sorry, I need a v3. First, we need a Signed-off-by line. Second, please use git send-email to post patches as the whitespace was broken still. Finally, please make sure that your commit message (when you do for example git show) explains the problem and the fix. In your v1 you had:
When using the load command with a btrfs filesystem, the return code of that command if always success even if the command failed. The problem is the do_load command in fs.c who assume any positive return code from fs_read as success. However the brtfs read function returns positive error code in case of failure. Other fs read fonction like fat and ext4 returns negative error codes on failure. So this patch change the return code of the btrfs read function to be consistent with other read functions. This way it will be possible to use the return code in the Hush shell with btrfs file systems as with other filesystems.

And aside from the typo of fonction rather than function, would make a good message. I'd have fixed this myself but then I noticed the missing Signed off by line. Thanks again!
