Okay, that won't be a problem at all.

Hi Mathias,
thanks for the good help and no problem with the Signed-off-by line. If you don't object we will just add a "Signed-off-by: Mathias Tillman master.homer@gmail.com master.homer@gmail.com" line when we push this patch to the repository.
It's just for tracking who created which code and who might know why something is implemented as it is, but since it's rather obvious what's wrong here there probably won't be any more questions about his.
I honestly don't remember if I have commit access to libdrm myself, but going to check. If not Alex or somebody else need to commit this.
Regards, Christian.

Sorry, no I am not a developer working on libdrm, this is my first contribution to it in fact. How would I go about adding my Signed-Off?

Agreed. Just was not quite sure if Mathias is working on the libdrm project directly or not based on the comments in the bugzilla "hopefully the fix can be pushed to master soon".
Regards, Jammy

For readdir_r(), the next directory entry is returned in caller-allocted buffer (pointered by pent here).
