Subject: [PATCH] md: add a missing endianness conversion in check_sb_changes
Git-commit: ed4d0a4ea11e19863952ac6a7cea3bbb27ccd452
Patch-mainline: v5.2-rc1
References: bsc#1166003
The on-disk value is little endian and we need to convert it to
native endian before storing the value in the in-core structure.
Fixes: 7564beda19b36 ("md-cluster/raid10: support add disk under grow mode")
