Subject: [merged] lz4-fix-compression-decompression-signedness-mismatch.patch removed from -mm tree To: sergey.senozhatsky@xxxxxxxxx,geert@xxxxxxxxxxxxxx,kyungsik.lee@xxxxxxx,yann.collet.73@xxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Thu, 12 Sep 2013 12:51:09 -0700 The patch titled Subject: lz4: fix compression/decompression signedness mismatch has been removed from the -mm tree. Its filename was lz4-fix-compression-decompression-signedness-mismatch.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Sergey Senozhatsky <sergey.senozhatsky@xxxxxxxxx> Subject: lz4: fix compression/decompression signedness mismatch LZ4 compression and decompression functions require different in signedness input/output parameters: unsigned char for compression and signed char for decompression. Change decompression API to require "(const) unsigned char *".
