Reverting in 4.19.3 and testing that would be ideal, though it would 
probably revert just fine in the lastest tree. If yuive been         
building from a git tree, then:                                      

$ git revert 5ebac3b957a9                                            

and rebuild is all you need to do (assuming it cleanly reverts).                

If you've been building from a downloaded tarball, then you'll need to apply
the revert yourself. I'll attach a revert patch, which you can apply via:

$ patch -p1 < revert.patch

and rebuild the kernel (assuming it applies cleanly - use --dry-run to test).

Or you can just manually change the code in an editor to set the code back to
the original. i.e:

        /* recently referenced inodes get one more pass */
        if (inode->i_state & I_REFERENCED) {
