This patch introduces reserve_new_blocks to make preallocation of multi
blocks as in batch operation, so it can avoid lots of redundant
operation, result in better performance.
In virtual machine, with rotational device:
time fallocate -l 32G /mnt/f2fs/file
Before:
real0m4.584s

This patch introduces reserve_new_blocks to make preallocation of multi
blocks as in batch operation, so it can avoid lots of redundant
operation, result in better performance.
