From c7bc6319c59cc791743cf1b6e98f86be69444495 Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Mon, 3 Nov 2014 14:12:57 +0000 Subject: [PATCH] Btrfs: avoid premature -ENOMEM in clear_extent_bit() We try to allocate an extent state structure before acquiring the extent state tree's spinlock as we might need a new one later and therefore avoid doing later an atomic allocation while holding the tree's spinlock. However we returned -ENOMEM if that initial non-atomic allocation failed, which is a bit excessive since we might end up not needing the pre-allocated extent state at all - for the case where the tree doesn't have any extent states that cover the input range and cover too any other range. Therefore don't return -ENOMEM if that pre-allocation fails. Signed-off-by: Filipe Manana Signed-off-by: Chris Mason --- Reading git-format-patch failed
