Now that we no longer try to reserve metadata blocks for delayed allocations (which tended to overestimate the required number of blocks significantly), we really don't need retry allocations when the disk is very full as aggressively any more. The only time when it makes sense to retry an allocation is if we have freshly deleted blocks that will only become available after a transaction commit. And if we lose that race, it's not worth it to try more than once. 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.
