Subject: Re: [PATCH] fs/ntfs3: fix build without CONFIG_NTFS3_LZX_XPRESS

Hi

This build regression also shows up, along with other problems, in a report to the ntfs3 list by the kernel test robot.[1]

Also, as this patch seems not to have been picked up by the NTFS3 maintainer I've added Thorsten Leemhuis so he can
consider adding this egression to the tracker.
