From af6d7b760c7547c1a410a333bdb24daed24e1043 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 11 May 2011 14:51:19 +1000 Subject: [PATCH] md/raid1: improve handling of pages allocated for write-behind. The current handling and freeing of these pages is a bit fragile. We only keep the list of allocated pages in each bio, so we need to still have a valid bio when freeing the pages, which is a bit clumsy. So simply store the allocated page list in the r1_bio so it can easily be found and freed when we are finished with the r1_bio. Signed-off-by: NeilBrown --- Reading git-format-patch failed
