Currently scrub is the only consumer. Thanks, Arne Arne Jansen (7): btrfs: add an extra wait mode to read_extent_buffer_pages btrfs: add READAHEAD extent buffer flag btrfs: state information for readahead btrfs: initial readahead code and prototypes btrfs: hooks for readahead btrfs: test ioctl for readahead btrfs: use readahead API for scrub fs/btrfs/Makefile | 3 +- fs/btrfs/ctree.h | 21 ++ fs/btrfs/disk-io.c | 85 +++++- fs/btrfs/disk-io.h | 2 + fs/btrfs/extent_io.c | 9 +- fs/btrfs/extent_io.h | 4 + fs/btrfs/ioctl.c | 93 +++++- fs/btrfs/ioctl.h | 16 + fs/btrfs/reada.c | 949 ++++++++++++++++++++++++++++++++++++++++++++++++++ fs/btrfs/scrub.c | 116 +++---- fs/btrfs/volumes.c | 8 + fs/btrfs/volumes.h | 8 + 12 files changed, 1239 insertions(+), 75 deletions(-) create mode 100644 fs/btrfs/reada.c
