  "message": "[PATCH] zlib_inflate: Upgrade library code to a recent version\n\nUpgrade the zlib_inflate implementation in the kernel from a patched\nversion 1.1.3/4 to a patched 1.2.3.\n\nThe code in the kernel is about seven years old and I noticed that the\nexternal zlib library\u0027s inflate performance was significantly faster (~50%)\nthan the code in the kernel on ARM (and faster again on x86_32).\n\nFor comparison the newer deflate code is 20% slower on ARM and 50% slower\non x86_32 but gives an approx 1% compression ratio improvement.  I don\u0027t\nconsider this to be an improvement for kernel use so have no plans to\nchange the zlib_deflate code.\n\nVarious changes have been made to the zlib code in the kernel, the most\nsignificant being the extra functions/flush option used by ppp_deflate.\nThis update reimplements the features PPP needs to ensure it continues to\nwork.\n\nThis code has been tested on ARM under both JFFS2 (with zlib compression\nenabled) and ppp_deflate and on x86_32.  JFFS2 sees an approx.  10% real\nworld file read speed improvement.\n\nThis patch also removes ZLIB_VERSION as it no longer has a correct value.\nWe don\u0027t need version checks anyway as the kernel\u0027s module handling will\ntake care of that for us.  This removal is also more in keeping with the\nzlib author\u0027s wishes (http://www.zlib.net/zlib_faq.html#faq24) and I\u0027ve\nadded something to the zlib.h header to note its a modified version.\n\nSigned-off-by: Richard Purdie \u003crpurdie@rpsys.net\u003e\nAcked-by: Joern Engel \u003cjoern@wh.fh-wedel.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
