In this cycle, Intel QAT hardware accelerators are supported to improve DEFLATE decompression performance. I've also tested it with the enwik9 dataset of 1 MiB pclusters on our Intel Sapphire Rapids bare-metal server and a PL0 ESSD, and the sequential read performance even surpasses LZ4 software decompression on this setup. In addition, a `fsoffset` mount option is introduced for file-backed mounts to specify the filesystem offset in order to adapt customized container formats. There are other improvements and minor cleanups shown as below. All commits have been in -next, and no potential merge conflicts are observed.
