Berrangé <berrange@redhat.com> This series solves a problem that Fedora has with creating btrfs volumes inside a mock chroot using qemu-user. Regards, Daniel
This series covers support for following btrfs ioctls *BTRFS_SUBVOL_CREATE *BTRFS_IOC_ADD_DEV *BTRFS_SUBVOL_SETFLAGS *BTRFS_IOC_RM_DEV *BTRFS_SUBVOL_GETFLAGS *BTRFS_IOC_DEV_INFO *BTRFS_GET_SUBVOL_INFO *BTRFS_IOC_GET_DEV_STATS *BTRFS_IOC_SNAP_CREATE *BTRFS_IOC_GET_FEATURES *BTRFS_IOC_SNAP_DESTROY *BTRFS_IOC_SET_FEATURES *BTRFS_IOC_SCAN_DEV *BTRFS_IOC_GET_SUPPORTED_FEATURES *BTRFS_IOC_DEFAULT_SUBVOL *BTRFS_IOC_QUOTA_RESCAN *BTRFS_IOC_GET_SUBVOL_ROOTREF *BTRFS_IOC_QUOTA_RESCAN_WAIT *BTRFS_IOC_QUOTA_CTL *BTRFS_IOC_SCRUB *BTRFS_IOC_QGROUP_CREATE *BTRFS_IOC_SCRUB_CANCEL *BTRFS_IOC_QGROUP_ASSIGN *BTRFS_IOC_SCRUB_PROGRESS *BTRFS_IOC_INO_PATHS *BTRFS_IOC_QGROUP_LIMIT *BTRFS_IOC_LOGICAL_INO *BTRFS_IOC_QUOTA_RESCAN_STATUS *BTRFS_IOC_LOGICAL_INO_V2 *BTRFS_IOC_INO_LOOKUP_USER *BTRFS_IOC_INO_LOOKUP The functionalities of individual ioctls were described in this series patch commit messages. Since all of these ioctls are added in kernel version 3.9, their definitions in file 'linux-user/ioctls.h' are enwrapped in an #ifdef directive. Testing method: Mini test programs were written for these ioctls. These test programs can be found on a repositort which is located on the link: https://github.com/bozutaf/btrfs-tests These test programs were compiled (sometimes using cross compilers) for following architectures: * Intel 64-bit (little endian) * Power pc 32-bit (big endian) * Power pc 64-bit (big endian) The corresponding native programs were executed without using QEMU on an intel x86_64 host. All applicable compiled programs were in turn executed through QEMU and the results obtained were the same ones gotten for native execution. v2: * Merged two series in one 8 patch series * Changed target ioctl definitions from IOR/IOW/IOWR to IORU/IOWU/IOWRU * Fixed some thunk struct definitions v3: * Added some checks in fine 'syscall_types.h' to see whether the ioctls that use the defined thunk types are present. This is done to support systems that have older versions of 'btrfs.h' file or if the file is not present at all. This is neccesary as to not cause build errors as some structures depend on values which are defined in 'btrfs.h'.
