From 03c902e17f40cfed63cd2494616f35fc9c58571b Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 6 Jan 2006 00:20:46 -0800 Subject: [PATCH] md: fix rdev->pending counts in raid1 When we do a user-requested check/repair, we lose count of the outstanding requests... Also make sure that when anything is written to md/sync_action, the RECOVERY_NEEDED flag is set and the thread is woken up so any changes take effect.
