Hi Gushengxian,
The code change looks good. A couple of cleanups noted below... (same feedback on next patch too) On Fri, Jun 25, 2021 at 12:27:00AM -0700, [email protected] wrote: > From: gushengxian <[email protected]> > > NULL check before vfree() is not needed. The commit message needs to say what was done, not the why. Example: "[PATCH] tools/testing/nvdimm: Remove NULL test before vfree" Then, the commit log explains why this should be done. Example: "This NULL test is redundant since vfree() checks for NULL." Coccinelle reports this vfree() case. If you did use Coccinelle to find it, please mention that in the commit log. Example: "Reported by Coccinelle." > > Signed-off-by: gushengxian <[email protected]> The email addresses don't match ([email protected], [email protected]) and it's not clear that you are using your full, legal name in the 'name line.
