From 8ccf6f19b67f7e0921063cc309f4672a6afcb528 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Thu, 25 Oct 2012 09:28:04 +0000 Subject: Btrfs: make delalloc inodes be flushed by multi-task This patch introduce a new worker pool named "flush_workers", and if we want to force all the inode with pending delalloc to the disks, we can queue those inodes into the work queue of the worker pool, in this way, those inodes will be flushed by multi-task.
