Hi Jaegeuk & Namjae, Sure, we'll address your comments. And this version is RFC, just wanna to make sure this feature is meaningful for f2fs project, and there is no obvious mistake, e.g. missing some critical path.
And if you team has some special opensource test suites used in your daily f2fs test cycle, pls. kindly share the info with us, then we can make sure our patchset can pass these cases before we send out next version. BTW, test the kernel source tree or kernel build is a good suggestion. thanks. On Tue, Jun 04, 2013 at 01:23:57PM +0900, Namjae Jeon wrote: > Hi.
