From d8086876a74743db2191a62c5a75e344c907143f Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Thu, 25 Jun 2015 23:22:36 -0700 Subject: lzma: Return correct amount of decompressed bytes The LZMA functions are supposed to return the decompressed size, but what they actually return is just an unaltered field from the LZMA header that is *supposed* to contain the decompressed size. Apparently some encoders just overshoot that for no good reason. This patch changes the code such that the actual amount of decompressed bytes is returned. BRANCH=smaug BUG=None TEST=Printed output bytes when decompressing kernels with LZMA in depthcharge, noted that amounts now make sense.
