Squashfs: Check stream is not NULL in decompressor_multi.c (2013-11-20 03:59:20 +0000)
---------------------------------------------------------------- These patches optionally improve the multi-threading peformance of Squashfs by adding parallel decompression, and direct decompression into the page cache, eliminating an intermediate buffer (removing memcpy overhead and lock contention).
---------------------------------------------------------------- Minchan Kim (1): squashfs: Enhance parallel I/O
Phillip Lougher (6): Squashfs: Refactor decompressor interface and code Squashfs: add multi-threaded decompression using percpu variable Squashfs: Generalise paging handling in the decompressors Squashfs: Restructure squashfs_readpage() Squashfs: Directly decompress into the page cache for file data Squashfs: Check stream is not NULL in decompressor_multi.c
