I was referring to the documentation mount() where it says that the call can return something other than the root dentry. More specifically, I don't understand how the what's the purpose of the if condition checking for s_root in mount_bdev(). Apologies if this is a trivial question. Tracking the calls all the way down didn't seem to make it clearer and I couldn't find specific documentation about the interface. > Also please include the kernel version to which you are referring. I have the 4.12-rc5 kernel. --- Shrikant _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
