[f2fs-dev][PATCH 1/4] f2fs: fix to enable readahead for SSA/CP blocks

2014-12-07 Thread Chao Yu
1.We use zero as upper boundary value for ra SSA/CP blocks, we will skip readahead as verification failure with max number, it causes low performance. 2.Low boundary value is not accurate for SSA/CP/POR region verification, so these values need to be redefined. This patch fixes above issues.
