f2fs: fix m_may_create to make OPU DIO write correctly
Previously, we added a parameter @map.m_may_create to trigger OPU
allocation and call f2fs_balance_fs() correctly.
But in get_more_blocks(), @create has been overwritten by below code.
So the function f2fs_map_blocks() will not allocate new block address
but directly go out. Meanwile,there are several functions calling
f2fs_map_blocks() directly and @map.m_may_create not initialized.
CODE:
create = dio->op == REQ_OP_WRITE;
if (dio->flags & DIO_SKIP_HOLES) {
if (fs_startblk <= ((i_size_read(dio->inode) - 1) >>
i_blkbits))
create = 0;
}
This patch fixes it.
