support that - since because the sequence number is zero-padded,
the numerical and alphabetic sort is the same.
See further details on how to phrase the "<explanation>" in the
"Subject:" line in Andrew Morton's "The perfect patch", referenced
below.
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,

default y
---help---
If you say Y here, you will get support for terminal devices with
display and keyboard devices. These are called "virtual" because you
can run several virtual terminals (also called virtual consoles) on
one physical terminal. This is rather useful, for example one
virtual terminal can collect system messages and warnings, another
one can be used for a text-mode user session, and a third could run
an X session, all in parallel. Switching between virtual terminals
is done with certain key combinations, usually Alt-<function key>.
The setterm command ("man setterm") can be used to change the
properties (such as colors or beeping) of a virtual terminal. The
man page console_codes(4) ("man console_codes") contains the special
character sequences that can be used to change those properties
directly. The fonts used on virtual terminals can be changed with
the setfont ("man setfont") command and the key bindings are defined
with the loadkeys ("man loadkeys") command.
You need at least one virtual terminal device in order to make use
of your keyboard and monitor. Therefore, only people configuring an
embedded system would want to say N here in order to save some
memory; the only way to log into such a system is then via a serial
or network connection.
If unsure, say Y, or else you won't be able to do much with your new
shiny Linux system :-)
config VT_CONSOLE
bool
default y
---help---
The system console is the device which receives all kernel messages
and warnings and which allows logins in single user mode. If you
answer Y here, a virtual terminal (the device used to interact with
a physical terminal) can be used as system console. This is the most
common mode of operations, so you should say Y here unless you want
the kernel messages be output only to a serial port (in which case
you should say Y to "Console on serial port", below).
If you do say Y here, by default the currently visible virtual
terminal (/dev/tty0) will be used as system console. You can change
that with a kernel command line option such as "console=tty3" which
would use the third virtual terminal as system console. (Try "man
bootparam" or see the documentation of your boot loader (lilo or
loadlin) about how to pass options to the kernel at boot time.)
If unsure, say Y.

inode instead of a vfs inode as parameter.
- Fix the definition of the CHKD ntfs record magic. It had an off by
two error causing it to be CHKB instead of CHKD.
- Fix a stupid bug in __ntfs_bitmap_set_bits_in_run() which caused the
count to become negative and hence we had a wild memset() scribbling
all over the system's ram.
2.1.23 - Implement extension of resident files and make writing safe as well as
many bug fixes, cleanups, and enhancements...
