[PATCH v2 05/11] md: match the type of variables to percpu_ref

From: tada keisuke
Date: Thu Apr 18 2024 - 02:42:02 EST


This patch depends on patch 04.

The counter size of percpu_ref is different from that of atomic_t.
This is the only place where the value of nr_pending is read.
The others are used for zero check and type has no effect.
