Cold files may be fragmented due to SSR, defragment is needed as
sequential reads are dominant scenarios of these files. FI_OPU_WRITE
should override FADVISE_COLD_BIT to avoid defragment fails.

Because the set/clear SBI_IS_RESIZEFS flag not between any locks,
there is a race:
thread1 thread2
ioctl(resizefs)
set RESIZEFS flag ioctl(resizefs)
... set RESIZEFS flag
...
clear RESIZEFS flag # then no RESIZEFS flag on thread2
We can start freeing cluster page(s) from which compression
is not used. It will get better performance.
