Don't alloc new page array to replace old, just use old page array, try
to reduce one page array alloc and free when write compress page.

Make f2fs_file_read_iter() and f2fs_file_write_iter() use the iomap
direct I/O implementation instead of the fs/direct-io.c one.
The iomap implementation is more efficient, and it also avoids the need
to add new features and optimizations to the old implementation.
This new i
This series makes f2fs use the iomap direct I/O implementation instead
of the fs/direct-io.c one. In order to do this, it adds f2fs_iomap_ops,
since this is the first use of iomap in f2fs.
The iomap direct I/O implementation is more efficient than
fs/direct-io.c. Switching to iomap also avoids t
From: Eric Biggers
Implement 'struct iomap_ops' for f2fs, in preparation for making f2fs
use iomap for direct I/O.
Note that this may be used for other things besides direct I/O in the
future; however, for now I've only tested it for direct I/O.

When we print out a discontinuous compression chunk, it shows like a
continuous chunk now. To show it more correctly, I've changed the way of
printing fiemap info like below. Plus, eliminated NEW_ADDR(-1) in fiemap
info, since it is not in fiemap user api manual.
