Currently, we have only 1024 free sba_request created by sba_prealloc_channel_resources(). This is too low and the prep_xxx() callbacks start failing more often at time of RAID array setup over NVMe disks. This patch sets number of free sba_request created by sba_prealloc_channel_resources() to be: <number_of_mailbox_channels> x 8192 Due to above, we will have sufficient number of free sba_request and prep_xxx() callbacks failing is very unlikely.

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.
