ceph_reserve_caps() may not reserve enough caps under high memory pressure, but it saved the needed caps number that expected to be reserved. When getting caps, crash would happen due to number mismatch. Now we will try to trim more caps when failing to allocate memory for caps need to be reserved, then try again. If still failing to allocate memory, return -ENOMEM.

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.
