According to `man blockdev':
--getsize
Print device size (32-bit!) in sectors.
Deprecated in favor of the --getsz option.
...
--getsz
Get size in 512-byte sectors.Hence, occurrences of `--getsize' should be replaced with `--getsz',
which this commit has achieved as follows:$ cd "$repo"
$ git grep -l -e --getsz

Add support for quickly loading a repetitive pattern into the
dm-switch target.In the "set_regions_mappings" message, the user may now use "Rn,m" as
one of the arguments. "n" and "m" are hexadecimal numbers. The "Rn,m"
argument repeats the last "n" arguments in the following "m" slots.For example:
dmsetup message switch 0 set_region_mappings 1000:1 :2 R2,10
is equivalent to
dmsetup message switch 0 set_region_mappings 1000:1 :2 :1 :2 :1 :2 :1 :2 \
:1 :2 :1 :2 :1 :2 :1 :2 :1 :2Requested-by: Jay Wang

dm-switch is a new target that maps IO to underlying block devices
efficiently when there is a large number of fixed-sized address regions
but there is no simple pattern to allow for a compact mapping
representation such as dm-stripe.Though we have developed this target for a specific storage device, Dell
EqualLogic, we have made an effort to keep it as general purpose as
possible in the hope that others may benefit.Originally developed by Jim Ramsay. Simplified by Mikulas Patocka.
