Vincent Whitchurch 08bab74ae6 squashfs: fix cache race with migration ... Migration replaces the page in the mapping before copying the contents and the flags over from the old page, so check that the page in the page cache is really up to date before using it. Without this, stressing squashfs reads with parallel compaction sometimes results in squashfs reporting data corruption.
