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 discussions are in [1] and [2].
[1] https://lore.kernel.org/all/CAJMQK-g9G6KQmH-V=BRGX0swZji9Wxe_2c7ht-MMAapdFy2pXw@mail.gmail.com/T/ [2] https://lore.kernel.org/linux-mm/Yn5Yij9pRPCzDozt@casper.infradead.org/t/#m4af4473b94f98a4996cb11756b633a07e5e059d1
This version is based on next-20220610 and the following series: "Squashfs: handle missing pages decompressing into page cache" [3].
This version is a refresh of ca1505bf4805 ("squashfs: implement readahead") and 9d58b94aa73a ("squashfs: always build "file direct" version of page actor").
There's no change in 4af2bd190a5b7 (Revert "squashfs: provide backing_dev_info in order to disable read-ahead"), but it's carried in this version too for consistency.
