# Script to apply kernel patches.

#   usage: patch-kernel [ sourcedir [ patchdir [ stopversion ] [ -acxx ] ] ]

#     The source directory defaults to /usr/src/linux, and the patch

#     directory defaults to the current directory.

# e.g.

#   scripts/patch-kernel . ..

#      Update the kernel tree in the current directory using patches in the

#      directory above to the latest Linus kernel

#   scripts/patch-kernel . .. -ac

#      Get the latest Linux kernel and patch it with the latest ac patch

#   scripts/patch-kernel . .. 2.4.9

#      Gets standard kernel 2.4.9

#   scripts/patch-kernel . .. 2.4.9 -ac

#      Gets 2.4.9 with latest ac patches

#   scripts/patch-kernel . .. 2.4.9 -ac11

#      Gets 2.4.9 with ac patch ac11

#   Note: It uses the patches relative to the Linus kernels, not the

#   ac to ac relative patches

#

# It determines the current kernel version from the top-level Makefile.

# It then looks for patches for the next sublevel in the patch directory.

# This is applied using "patch -p1 -s" from within the kernel directory.

# A check is then made for "*.rej" files to see if the patch was

# successful.  If it is, then all of the "*.orig" files are removed.

#

# Added support for handling multiple types of compression. What includes

# gzip, bzip, bzip2, zip, compress, and plaintext.

#

#       Adam Sulmicki <adam@cfar.umd.edu>, 1st January 1997.

#

# Added ability to stop at a given version number

# Put the full version number (i.e. 2.3.31) as the last parameter

#       Dave Gilbert <linux@treblig.org>, 11th December 1999.

​

# Fixed previous patch so that if we are already at the correct version

# not to patch up.

#

# Added -ac option, use -ac or -ac9 (say) to stop at a particular version

#       Dave Gilbert <linux@treblig.org>, 29th September 2001.

#

# Add support for (use of) EXTRAVERSION (to support 2.6.8.x, e.g.);

# update usage message;

# fix some whitespace damage;

# be smarter about stopping when current version is larger than requested;

#   Randy Dunlap <rdunlap@xenotime.net>, 2004-AUG-18.

#

# Add better support for (non-incremental) 2.6.x.y patches;

# If an ending version number if not specified, the script automatically

# increments the SUBLEVEL (x in 2.6.x.y) until no more patch files are found;

# however, EXTRAVERSION (y in 2.6.x.y) is never automatically incremented

# but must be specified fully.

#

# patch-kernel does not normally support reverse patching, but does so when

# applying EXTRAVERSION (x.y) patches, so that moving from 2.6.11.y to 2.6.11.z

# is easy and handled by the script (reverse 2.6.11.y and apply 2.6.11.z).

#   Randy Dunlap <rdunlap@xenotime.net>, 2005-APR-08.
