   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).
