Linux Kernel Patch Submission Format
====================================
-Most Linux kernel submissions are merged into the kernel source code repository by script. These instructions describe the proper format for emailed kernel patch submissions, to ensure that submittors and maintainers waste a minimum amount of time on these details.

[PATCH $version $n/$total] $subsystem: one-line summary
"[PATCH": constant prefix
$version: kernel version against which this patch was generated
- $n/$total: when a change encompasses more than one patch, $n indicates the order of this patch in the series, and $total indicates the total number of patches in the series.
- $subsystem: area of the kernel, or device driver, to which this patch applies.
- one-line summary: summarizes the change this patch makes. This summary is copied directly into the SCM (i.e. git) changelog, so make sure that your summary is descriptive. Ensure that $subsystem uniquely identifies the subsystem or driver being modified. "update to latest CVS" or "fix bug in probe" is not specific enough about what portion of the code is being modified.

6. Avoid attachments and MIME
+=============================
+Attachments make it more difficult to review and comment on your patches. MIME
+(the mechanism by which files are attached to an email) has historically
+created a problem for patch import scripts. Some unfortunate email programs
+insist upon base64 encoding for all attachments, which completely shrouds the

7. Follow these instructions even when resending
-
-Quite often, when a patch receives comments, the patch author will (deep in an email thread) include a revised version of their patch but omit the email subject one-line summary, and overall patch description. This isn't script friendly, and requires the patch description to be hand-edited.
