Hi Naresh, thanks for reporting!

Whoa, I really didn't expect this.

I named the variable pmd_val, and during the expansion of pte_offset_map_lock(), we call pmd_val(), and the compiler is confused because it's calling a variable rather than a function or macro.

And it didn't show up on my testing environment because on x86_64 implementation of pte_offset_map_lock() implementation we don't call pmd_val(). The fix would be simply renaming the variable.

To Greg and Sasha; I guess these patches will be dropped for this cycle and I'm supposed to send V2, right? These two patches are queued for 6.1, 5.15, 5.10 as well.

I tried my best to make sure these backports are properly tested, and apologies for the inconvenience that I caused.

Cheers,
Harry / Hyeonggon

Ok, I'll go drop these from all of these branches now and wait for a v2.

I'll also push out a -rc3.

thanks,

greg k-h

Hi Greg,

No problems seen on x86_64 and aarch64 with our testing.

Thanks,
