Build-server workloads have hundreds of references per file after dedup. Multiply by a few snapshots and we quickly exhaust the limit of 2730 references per extent that can fit into a 64K buffer. Raise the limit to 16M to be consistent with other btrfs ioctls (e.g. TREE_SEARCH_V2, FILE_EXTENT_SAME). To minimize surprising userspace behavior, apply this change only to the LOGICAL_INO_V2 ioctl.

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.
