Bruce Fields" Date: Wed, 16 Sep 2015 17:21:27 -0400 Subject: nfs: fix v4.2 SEEK on files over 2 gigs From: "J. Bruce Fields" commit 306a5549355966e480e0dcacdc6b9321d153e0c0 upstream. We're incorrectly assigning a loff_t return to an int. If SEEK_HOLE or SEEK_DATA returns an offset over 2^31 then the application will see a weird lseek() result (usually -EIO).
