Subject: mm/compaction: improve comment for compact_memory tunable knob handler
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fec4eb2c8d89bf8d18136df3d688c42b7959a057;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mm/compaction: improve comment for compact_memory tunable knob handler

sysctl_compaction_handler() is the handler function for compact_memory
tunable knob under /proc/sys/vm, add the missing knob name to make this
more accurate in comment.

No functional change.
