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.
