-12) The canonical patch format
 
-The canonical patch subject line is:
-
-    Subject: [PATCH 001/123] subsystem: summary phrase
-
-The canonical patch message body contains the following:
-
-  - A "from" line specifying the patch author.
-
-  - An empty line.
-
-  - The body of the explanation, which will be copied to the
-    permanent changelog to describe this patch.
-
-  - The "Signed-off-by:" lines, described above, which will
-    also go in the changelog.
-
-  - A marker line containing simply "---".
-
-  - Any additional comments not suitable for the changelog.
-
-  - The actual patch (diff output).
-
-The Subject line format makes it very easy to sort the emails
-alphabetically by subject line - pretty much any email reader will
-support that - since because the sequence number is zero-padded,
-the numerical and alphabetic sort is the same.
-
-The "subsystem" in the email's Subject should identify which
-area or subsystem of the kernel is being patched.
-
-The "summary phrase" in the email's Subject should concisely
-describe the patch which that email contains.  The "summary
-phrase" should not be a filename.  Do not use the same "summary
-phrase" for every patch in a whole patch series.
-
-Bear in mind that the "summary phrase" of your email becomes
-a globally-unique identifier for that patch.  It propagates
-all the way into the git changelog.  The "summary phrase" may
-later be used in developer discussions which refer to the patch.
-People will want to google for the "summary phrase" to read
-discussion regarding that patch.
-
-A couple of example Subjects:
-
-    Subject: [patch 2/5] ext2: improve scalability of bitmap searching
-    Subject: [PATCHv2 001/207] x86: fix eflags tracking
-
-The "from" line must be the very first line in the message body,
-and has the form:
-
-        From: Original Author <author@example.com>
-
-The "from" line specifies who will be credited as the author of the
-patch in the permanent changelog.  If the "from" line is missing,
-then the "From:" line from the email header will be used to determine
-the patch author in the changelog.
-
-The explanation body will be committed to the permanent source
-changelog, so should make sense to a competent reader who has long
-since forgotten the immediate details of the discussion that might
-have led to this patch.
-
-The "---" marker line serves the essential purpose of marking for patch
-handling tools where the changelog message ends.
-
-One good use for the additional comments after the "---" marker is for
-a diffstat, to show what files have changed, and the number of inserted
-and deleted lines per file.  A diffstat is especially useful on bigger
-patches.  Other comments relevant only to the moment or the maintainer,
-not suitable for the permanent changelog, should also go here.

@@ -131,47 +131,3 @@ Netlink itself is not reliable protocol, that means that messages can

-Userspace usage.
-/*****************************************/
-2.6.14 has a new netlink socket implementation, which by default does not
-allow to send data to netlink groups other than 1.
-So, if to use netlink socket (for example using connector) 
-with different group number userspace application must subscribe to 
-that group. It can be achieved by following pseudocode:
-
-s = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
-
-l_local.nl_family = AF_NETLINK;
-l_local.nl_groups = 12345;
-l_local.nl_pid = 0;

-	perror("bind");
-	close(s);
-	return -1;
-}
-
-{
-	int on = l_local.nl_groups;
-	setsockopt(s, 270, 1, &on, sizeof(on));
-}
-
-Where 270 above is SOL_NETLINK, and 1 is a NETLINK_ADD_MEMBERSHIP socket
-option. To drop multicast subscription one should call above socket option
-with NETLINK_DROP_MEMBERSHIP parameter which is defined as 0.
-
-2.6.14 netlink code only allows to select a group which is less or equal to
-the maximum group number, which is used at netlink_kernel_create() time.
-In case of connector it is CN_NETLINK_USERS + 0xf, so if you want to use
-group number 12345, you must increment CN_NETLINK_USERS to that number.
-Additional 0xf numbers are allocated to be used by non-in-kernel users.
-
-Due to this limitation, group 0xffffffff does not work now, so one can
-not use add/remove connector's group notifications, but as far as I know, 
-only cn_test.c test module used it.
-
-Some work in netlink area is still being done, so things can be changed in
-2.6.15 timeframe, if it will happen, documentation will be updated for that
-kernel.
