If the max open zones of zoned devices are less than
the active logs of F2FS, the device may error due to
insufficient zone resources when multiple active logs
are being written at the same time.

Some comments are confused and just correct with block size is 4KB.

After commit 899fee36fac0 ("f2fs: fix to avoid data corruption by

bitmap to avoid unnecessary calculation overhead whenever allocating
free slot w/ SSR allocator.

Currently, __exchange_data_block() will check checkpointed state of data,
if it is not checkpointed, it will try to exchange blkaddrs directly in

max open zone may be larger than log header number of f2fs, for
such case, it doesn't need to wait last IO in previous zone, let's
introduce available_open_zone semaphore, and reduce it once we
submit first write IO in a zone, and increase it after completion
of last IO in the zone.
