My home directory is an NFSv4 mount, and the problem appears on my client workstation, so this makes some sense: > sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) > pretzel:/ on /g type nfs4 (rw,noatime,proto=tcp,addr=10.10.10.1) As an aside, let me express the hope that the NFS developers develop better patch creation methods. My bisect compile repeatedly died at > CHK include/linux/version.h > CHK include/linux/utsrelease.h > CHK include/linux/compile.h > fs/nfs/pagelist.c:239: error: conflicting types for ‘nfs_pageio_init’ > include/linux/nfs_page.h:80: error: previous declaration of ‘nfs_pageio_init’ was here > make[2]: *** [fs/nfs/pagelist.o] Error 1 > make[1]: *** [fs/nfs] Error 2 > make: *** [fs] Error 2 which indicates that someone on the NFS team did not create wholly-contained patches when submitted to the kernel. Build breakage should not be fixed in a later commit (unless the breakage already went upstream), because -- as we see here -- it breaks bisection.
