[PATCH 3.12 158/170] ext4: clarify ext4_error message in ext4_mb_generate_buddy_error()

[Jiri Slaby]

From: Theodore Ts'o <tytso@xxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 94d4c066a4ff170a2671b1a9b153febbf36796f6 upstream.

We are spending a lot of time explaining to users what this error
means.  Let's try to improve the message to avoid this problem.
