Subject: [PATCH 0/2] squashfs: Add the mount parameter "threads="

Currently, Squashfs supports multiple decompressor parallel modes. However, this
mode can be configured only during kernel building and does not support flexible
selection during runtime.

In the current patch set, the mount parameter "threads=" is added to allow users
to select the parallel decompressor mode and configure the number of decompressors
when mounting a file system.

Xiaoming Ni (2):
  squashfs: add the mount parameter theads=<single|multi|percpu>
  squashfs: Allows users to configure the number of decompression
    threads.
