[PATCH] ext4: remove unnecessary duplicate check in ext4_map_blocks()
Posted by Dan Carpenter 6 months, 3 weeks ago
The previous lines ensure that EXT4_GET_BLOCKS_QUERY_LAST_IN_LEAF is
set so remove this duplicate check.

Earlier, I knew it was a redundant check, but I went ahead with it
anyway; and later, I might have missed removing it. I agree that we
don’t really need this extra check.

So, the patch looks good to me. Thanks for taking care of it!
