The AG inode iterator currently skips new inodes as such inodes are inserted into the inode radix tree before they are fully constructed. Certain contexts require the ability to wait on the construction of new inodes, however. The fs-wide dquot release from the quotaoff sequence is an example of this. Update the AG inode iterator to support the ability to wait on inodes flagged with XFS_INEW upon request. Create a new xfs_inode_ag_iterator_flags() interface and support a set of iteration flags to modify the iteration behavior. When the XFS_AGITER_INEW_WAIT flag is set, include XFS_INEW flags in the radix tree inode lookup and wait on them before the callback is executed.

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.
