Commit c1f6925e1091("mm: put readahead pages in cache earlier") requires fs to implement readahead callback. Otherwise there will be a performance regression.
Commit 9eec1d897139("squashfs: provide backing_dev_info in order to disable read-ahead") mitigates the performance drop issue for squashfs by closing readahead for it.
This series implements readahead callback for squashfs. The previous discussion are in [1] and [2].
