That is to say your patchset is probably an improvement, but this
benchmark uses kernfs which is a total crapper, with code like this in
kernfs_iop_permission:
root = kernfs_root(kn);
down_read(&root->kernfs_iattr_rwsem);
kernfs_refresh_inode(kn, inode);
ret = generic_permission(&nop_mnt_idmap, inode, mask);
up_read(&root->kernfs_iattr_rwsem);
Maybe there is an easy way to dodge this, off hand I don't see one.
If there are no other regressions found and there is no easy way out,
I would argue this should be ignored.
