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).

Phillip Lougher (6):
Squashfs: Refactor decompressor interface and code
Squashfs: add multi-threaded decompression using percpu variable

Squashfs: Directly decompress into the page cache for file data
Squashfs: Check stream is not NULL in decompressor_multi.c
