Commit v4.13-rc1~137^2~13 (and a follow-up fix v4.14-rc4~20^2~3
that changed alignment) introduced an additional hidden field
in the structure returned by DM_LIST_DEVICES ioctl command
that contains event_nr information.
Unfortunately, we can't test it for now, but looks like it kinda works:
# ./strace -v -eioctl -y dmsetup ls
ioctl(3</dev/mapper/control>, DM_VERSION, {version=4.0.0,
data_size=16384, flags=DM_EXISTS_FLAG} => {version=4.37.0,
data_size=16384, flags=DM_EXISTS_FLAG}) = 0
ioctl(3</dev/mapper/control>, DM_LIST_DEVICES, {version=4.0.0,
data_size=16384, data_start=312, flags=DM_EXISTS_FLAG} =>
{version=4.37.0, data_size=408, data_start=312, flags=DM_EXISTS_FLAG,
{dev=makedev(253, 1), name="fedoratesting--30-swap", event_nr=0},
{dev=makedev(253, 0), name="fedoratesting--30-root"}}) = 0
fedoratesting--30-swap (253:1)
fedoratesting--30-root (253:0)
* dm.c (dm_decode_dm_name_list): Obtain the amount of bytes copied
during printing device name, print event number if there's a suitable
gap present and the DM version is high enough.
* NEWS: Mention it.
Return RVAL_DECODED if we can't decode command in order to avoid being
called on exiting.
* dm.c (dm_ioctl): Return RVAL_DECODED instead of 0 if command can't be
decoded.
* print_dev_t.c: New file.

* dm.c: Do not include <sys/sysmacros.h>.
(dm_decode_device, dm_print_dev, dm_decode_dm_name_list): Use
print_dev_t function for printing device numbers.
* mknod.c: Do not include <sys/sysmacros.h>.
(decode_mknod): Use print_dev_t function for printing device number.
* print_struct_stat.c: Do not include <sys/sysmacros.h>.
(print_struct_stat): Use print_dev_t function for printing device
numbers.
