There is kernel side support for the creation of read-only snapshots for some time now, but I did not find any patches for the userspace btrfs utilites. Thus I created this patchset which is tested and working with kernel version 2.6.39-rc2. Andreas Philipp (5): Add support for read-only subvolumes. Support the new parameters in do_clone(int argc, char** argv). Added support for an additional ioctl. Test the additional ioctl. Updated documentation for btrfs subvolume snapshot. btrfs.c | 6 +++--- btrfs_cmds.c | 44 ++++++++++++++++++++++++++++++++++++-------- ioctl-test.c | 1 + ioctl.h | 14 ++++++++++++++ man/btrfs.8.in | 11 ++++++----- 5 files changed, 60 insertions(+), 16 deletions(-) -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
