From: Liu Bo <bo.li.liu@oracle.com> Date: Wed, 17 Jun 2015 16:59:58 +0800 Subject: Btrfs: fix warning of bytes_may_use Git-commit: ddba1bfc2369cd0566bcfdab47599834a32d1c19 Patch-mainline: v4.2-rc2 References: revisit While running generic/019, dmesg got several warnings from btrfs_free_reserved_data_space(). Test generic/019 produces some disk failures so sumbit dio will get errors, in which case, btrfs_direct_IO() goes to the error handling and free bytes_may_use, but the problem is that bytes_may_use has been free'd during get_block(). This adds a runtime flag to show if we've gone through get_block(), if so, don't do the cleanup work.
