Subject: md: fix formatting error in /proc/mdstat
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=52720ae77d392d3f4c12281c37304edbc8cb51f1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

md: fix formatting error in /proc/mdstat

If an md array is "auto-read-only", then this appears in /proc/mdstat as

   /dev/md0: active(auto-read-only)

whereas if it is truely readonly, it appears as

   /dev/md0: active (read-only)

The difference being a space.

One program known to parse this file expects the space and gets badly
confused.  It will be fixed, but it would be best if what the kernel generates
is more consistent too.
