The create transaction reservation calculation has two different branches of code depending on whether the filesystem is a v5 format fs or older. Each branch considers the max reservation between the allocation case (new chunk allocation + record insert) and the modify case (chunk exists, record modification) of inode allocation. The modify case is the same for both superblock versions with the exception of the finobt. The finobt helper checks the feature bit, however, and so the modify case already shares the same code. Now that inode chunk allocation has been refactored into a helper that checks the superblock version to calculate the appropriate reservation for the create transaction, the only remaining difference between the create and icreate branches is the call to the finobt helper. As noted above, the finobt helper is a no-op when the feature is not enabled. Therefore, these branches are effectively duplicate and can be condensed. Remove the xfs_calc_create_*() branch of functions and update the various callers to use the xfs_calc_icreate_*() variant. The latter creates the same reservation size for v4 create transactions as the removed branch. As such, this patch does not result in transaction reservation changes.

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.
