Simplify the definition of feat_map by introducing a helper macro FEAT_NAME to avoid having to type the feature name twice. As a side effect, this changes the names in the feature list to be the full macro name instead of the abbreviated names that were used before, but this is a good change for clarity. Using the full feature macro names ruins the alignment of the output, so change the output format to put each feature's hex value before its name, as this is easier to align nicely. The output now looks as follows: root# ./kublk features ublk_drv features: 0x7fff 0x1 : UBLK_F_SUPPORT_ZERO_COPY 0x2 : UBLK_F_URING_CMD_COMP_IN_TASK 0x4 : UBLK_F_NEED_GET_DATA 0x8 : UBLK_F_USER_RECOVERY 0x10 : UBLK_F_USER_RECOVERY_REISSUE 0x20 : UBLK_F_UNPRIVILEGED_DEV 0x40 : UBLK_F_CMD_IOCTL_ENCODE 0x80 : UBLK_F_USER_COPY 0x100 : UBLK_F_ZONED 0x200 : UBLK_F_USER_RECOVERY_FAIL_IO 0x400 : UBLK_F_UPDATE_SIZE 0x800 : UBLK_F_AUTO_BUF_REG 0x1000 : UBLK_F_QUIESCE 0x2000 : UBLK_F_PER_IO_DAEMON 0x4000 : unknown Signed-off-by: Uday Shankar <ushankar@purestorage.com> Reviewed-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |
