From a22285a6a32390195235171b89d157ed1a1fe932 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Sun, 16 May 2010 10:48:46 -0400 Subject: Btrfs: Integrate metadata reservation with start_transaction Besides simplify the code, this change makes sure all metadata reservation for normal metadata operations are released after committing transaction. Changes since V1: Add code that check if unlink and rmdir will free space. Add ENOSPC handling for clone ioctl.
