From c6b305a89b1903d63652691ad5eb9f05aa0326b8 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 18 Dec 2012 09:16:16 -0500 Subject: Btrfs: don't re-enter when allocating a chunk If we start running low on metadata space we will try to allocate a chunk, which could then try to allocate a chunk to add the device entry. The thing is we allocate a chunk before we try really hard to make the allocation, so we should be able to find space for the device entry. Add a flag to the trans handle so we know we're currently allocating a chunk so we can just bail out if we try to allocate another chunk.
