The patch titled Decompressors: get rid of set_error_fn() macro has been removed from the -mm tree. Its filename was decompressors-get-rid-of-set_error_fn-macro.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: Decompressors: get rid of set_error_fn() macro From: Lasse Collin <lasse.collin@xxxxxxxxxxx> set_error_fn() has become a useless complication after c1e7c3ae59 ("bzip2/lzma/gzip: pre-boot malloc doesn't return NULL on failure") fixed the use of error() in malloc(). Only decompress_unlzma.c had some use for it and that was easy to change too. This also gets rid of the static function pointer "error", which should have been marked as __initdata.
