Jaegeuk Kim b3fcb70064 f2fs: support IO alignment for DATA and NODE writes ... commit 0a595ebaaa6b53a2226d3fee2a2fd616ea5ba378 upstream. This patch implements IO alignment by filling dummy blocks in DATA and NODE write bios. If we can guarantee, for example, 32KB or 64KB for such the IOs, we can eliminate underlying dummy page problem which FTL conducts in order to close MLC or TLC partial written pages. Note that, - it requires "-o mode=lfs". - IO size should be power of 2, not exceed BIO_MAX_PAGES, 256. - read IO is still 4KB. - do checkpoint at fsync, if dummy NODE page was written.
