You miss proper diffstat which makes reviewing difficult.

Actually entire patch is corrupted and impossible to apply.

Anyway, where is any user of this? Nothing in commit msg explains this.

Keep description in one line and add a blank line. This code is not that

submitting-patches, organize your patchset correctly into manageable
logical chunks and send them as proper patchset, not one junk.
