Since we do a delalloc reserve in btrfs_truncate_block we can deadlock with freeze. If somebody else is trying to allocate metadata for this inode and it gets stuck in start_delalloc_inodes because of freeze we will deadlock. Be safe and move this outside of a trans handle. This also has a side-effect of making sure that we're not leaving stale data behind in the other_encoding or encryption case. Not an issue now since nobody uses it, but it would be a problem in the future. Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: David Sterba <dsterba@suse.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
