Rewrite xfs_bmap_collapse_extents so that we don't rely on extent indices
except for iterating over them. Not being able to iterate to the next
extent is a sufficient exit condition, and we don't need to do any extent
count games given that:
a) we already flushed all delalloc extents past our start offset
before doing the operation
b) xfs_iext_count() includes delalloc extents anyway

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.
