Subject[PATCH 0/4] mm: introduce fincore() v2
Date
This is the 2nd version of fincore patchset.

In the previous discussion[1], I got many feedbacks about the following
points:
- robust ABI handling is needed (especially about PAGECACHE_TAG_*)
- man page is necessary
- the parameter/return value of sys_fincore() needs improvement
- the order of bits FINCORE_* and the order of 8 bytes entry in buffer
should be identical
so I covered these in this version.

Any comments/reviews are welcomed.
