Denys Vlasenko b4c11c1397 libarchive: add capability to unpack to mem.buffer ... The performance and number of processes for a "depmod -a" with gzipped modules was abysmal. This patch adds a code path without fork, benefiting all users of xmalloc_open_zipped_read_close. "modinfo radeon.ko.gz", a single-file reader, got 30% faster. "depmod -a", which used to fork over 800 times, got 20% faster.
