Chris Mason 33b2580864 Btrfs: allow more metadata chunk preallocation ... On an FS where all of the space has not been allocated into chunks yet, the enospc can return enospc just because the existing metadata chunks are full. We get around this by allowing more metadata chunks to be allocated up to a certain limit, and finding the right limit is a little fuzzy. The problem is the reservations for delalloc would preallocate way too much of the FS as metadata. We need to start saying no and just force some IO to happen. But we also need to let a reasonable amount of the FS become metadata. This bumps the hard limit up, later releases will have a better system.
