Subject: dm thin metadata: remove unused dm_pool_get_data_block_size()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9cb1397d585c28c2acff06a6002fc2c8db19a80d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dm thin metadata: remove unused dm_pool_get_data_block_size()

The thin-pool target doesn't display the data block size as part of
its table status, unlike the dm-cache target, so there is no need for
dm_pool_get_data_block_size().

This was found using cppcheck.
