SubjectRe: [PATCH 2/2] f2fs: fix the case when there is no free segment to allocate for CURSEG_WARM_NODE
Hi Yunlong,

I already started to test this since a couple of days ago. :)

http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs.git/commit/?h=dev-test&id=908b5f463c82eaf972b149a26bb310f5e25064fd

Thanks,
