Subject: Re: [PATCH] jfs: Convert jfs_error to jfs_sb_err
I generally like this cleanup except for one thing.

Why the rename? If you're going to rename it, the new name should be
more descriptive, such as jfs_report_and_handle_error(), but I don't
like that because it's too long. jfs_error() is similiar to ext4_error()
or btrfs_error(). I don't understand the name change.

I like this.
