"Skip the f2fs test on ..." might be better wording, both in this
paragraph and the Subject.
Exit code 77 is certainly documented with the word "skip", and "exit
77" will show up in the "make check" output as "SKIP" as well.

This confusing to me. You are skipping the test when
PAGE_SIZE > F2FS_BLKSIZE
but the corresponding message says
PAGE_SIZE != F2FS_BLKSIZE
Now... which condition is it supposed to be? ">" or "!="?
I know from the Linux kernel's ext2 driver that it is very well
possible that PAGE_SIZE != EXT2_BLOCK_SIZE can work
unless EXT2_BLOCK_SIZE > PAGE_SIZE.
So ">" and "!=" are not necessarily the same thing, and IMHO the check
and the message use the same condition.
