From 4b82490649f5c8ecbf888752c325ea68831c497e Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Wed, 20 Feb 2013 09:13:32 +0000 Subject: [PATCH] Btrfs: fix the qgroup reserved space is released prematurely In start_transactio(), we will try to join the transaction again after the current transaction is committed, so we should not release the reserved space of the qgroup. Fix it.
