Applied, with that one "default n" line dropped. An ACK from Dave might also help reassure Linus I'm not stepping on anybody's toes. --b.

Instead of creeping pnfs layout configuration into filesystems, move the definition of block-based export operations under a more abstract configuration. Changes from v1: - dropped the first patch in the first posting - renamed the config to EXPORTFS_BLOCK_OPS from BLOCK_EXPORT_OPS - add an explicit default to no for EXPORTFS_BLOCK_OPS - add some help and menu text Signed-off-by: Benjamin Coddington <bcodding@redhat.com> --- fs/Kconfig | 7 +++++++ fs/nfsd/Kconfig | 2 ++ fs/xfs/Makefile | 3 +-- fs/xfs/xfs_export.c | 2 +- fs/xfs/xfs_pnfs.h | 4 ++-- 5 files changed, 13 insertions(+), 5 deletions(-)
