  To: linux-kernel, linux-fsdevel, linux-f2fs-devel; +Cc: Jaegeuk Kim

This patch replaces (f2fs_encrypted_inode() && S_ISREG()) with
f2fs_encrypted_file(), which gives no functional change.

This patch renames functions regarding to buffer management via META_MAPPING
used for encrypted blocks especially. We can actually use them in generic way.
