The patch titled
Subject: hwpoison: call action_result() in failure path of hwpoison_user_mappings()
has been removed from the -mm tree. Its filename was
hwpoison-call-action_result-in-failure-path-of-hwpoison_user_mappings.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Naoya Horiguchi <n-horiguchi@xxxxxxxxxxxxx>
Subject: hwpoison: call action_result() in failure path of hwpoison_user_mappings()
hwpoison_user_mappings() could fail for various reasons, so printk()s to
print out the reasons should be done in each failure check inside
hwpoison_user_mappings().
And currently we don't call action_result() when hwpoison_user_mappings()
fails, which is not consistent with other exit points of memory error
handler. So this patch fixes these messaging problems.
