146054090b085 introduced fs-verity support for btrfs, but didn't add support for FS_IOC_READ_VERITY_METADATA to directly query the Merkle tree, descriptor and signature blocks for fs-verity enabled files. Add the (trival) implementation: we just need to wire it through to the fs-verity code, the same way as is done in the other two filesystems which support this ioctl (ext4, f2fs). The fs-verity code already has access to the required data. Signed-off-by: Allison Karlitskaya <allison.karlitskaya@redhat.com> --- fs/btrfs/ioctl.c | 2 ++ 1 file changed, 2 insertions(+)
