During inode deletion, the number of journal credits that will be needed is hard to determine. For that reason we have journal extend/restart calls in several places. Whenever a transaction is restarted, filesystem must be in a consistent state because there is no atomicity guarantee beyond a restart call. Add ext4_xattr_ensure_credits() helper function which takes care of journal extend/restart logic. It also handles getting jbd2 write access and dirty metadata calls. This function is called at every iteration of handling an ea_inode reference. Signed-off-by: Tahsin Erdogan <tahsin@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
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.
