Previously, in getxattr we will load all entries both in inline xattr and xattr node block, and then do the lookup in all entries, but our lookup flow shows low efficiency, since if we can lookup and hit in inline xattr of inode page cache first, we don't need to load and lookup xattr node block, which can obviously save cpu time and IO latency.

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.
