Subject: mm/mempolicy: count MPOL_WEIGHTED_INTERLEAVE to "interleave_hit"
Date: Fri, 27 Dec 2024 18:57:37 +0900
Commit fa3bea4e1f82 introduced MPOL_WEIGHTED_INTERLEAVE but it missed
adding its counter to "interleave_hit" of numastat, which is located at
/sys/devices/system/node/nodeN/ directory.
It'd be better to add weighted interleving counter info to the existing
"interleave_hit" instead of introducing a new counter
"weighted_interleave_hit".
