Yes, this is the vm_fault_t changes. See the other thread on LKML. The guilty commit was: 83c0adddcc6e: fs: convert return type int to vm_fault_t This is the *second* time vm_fault_t patches have broken things. The first time it went through the ext4 tree, and I NACK'ed it after running a 60 second smoke test showed it was broken. The seocnd time the problem was supposedly fixed, but it went through the mm tree, and so I didn't have a chance regression test or stop it... - Ted
