Hello, here are two patches that implement extended attribute readahead for those cases where the extended attribute block is allocated immediately upon inode creation (i.e., with SELinux or inherited permissions). The first patch submits a READA request for the extended attributes after submitting a READ request for the inode.
The second patch submits both requests in a single bio instead. As you can see, this is somewhat messy. I'm not convinced that this optimization buys us anything, so I will not recommend merging this patch. Git tree: git://git.kernel.org/pub/scm/linux/kernel/git/agruen/linux.git gfs2-wip Could you please review?
