We should no longer need the inode->i_lock, now that we've straightened out the request locking. The locking schema is now: 1) Lock page head request 2) Lock the page group 3) Lock the subrequests one by one Note that there is a subtle race with nfs_inode_remove_request() due to the fact that the latter does not lock the page head, when removing it from the struct page. Only the last subrequest is locked, hence we need to re-check that the PagePrivate(page) is still set after we've locked all the subrequests.

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.
