zram: support priority parameter in recompression
recompress device attribute supports alg=NAME parameter so that we can
specify only one particular algorithm we want to perform recompression
with.
zram: support priority parameter in recompression
recompress device attribute supports alg=NAME parameter so that we can
specify only one particular algorithm we want to perform recompression
with. However, with algo params we now can have several exactly same
secondary algorithms but each with its own params tuning (e.g. priority 1
configured to use more aggressive level, and priority 2 configured to use
a pre-trained dictionary). Support priority=NUM parameter so that we can
correctly determine which secondary algorithm we want to use.

zram: add stat to gather incompressible pages since zram set up
Currently, zram supports the stat via /sys/block/zram/mm_stat to represent
how many of incompressible pages are stored at the moment but it couldn't
show how many times incompressible pages were wrote down since zram set
up. It's also good indication to see how zram is effective in the system.
