+        // FUSE filesystem. The reason this is in place is that FUSE
+        // filesystems shouldn't be trusted by default; a FUSE filesystem could
+        // take up say 100% of dirty pages, and subsequently refuse to write
+        // them back to storage.  The kernel will then apply rate-limiting, and
+        // block other tasks from writing.  For this particular FUSE filesystem
+        // however, we trust the implementation, because it is a part of the
+        // Android platform. So use the default ratio of 100%.

+        // The reason we're setting this is that there's a suspicion that the

+        // memory pressure scenarios. While the kernel will only rate limit if
+        // the writeback can't keep up with the write rate, under extreme
+        // memory pressure the write rate may dip as well, in which case FUSE
+        // writes to a 1% max_ratio filesystem are throttled to an extreme amount.
+        //
+        // To prevent this, just give FUSE 40% max_ratio, meaning it can take
