The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the node release code to a separate function broke death notifications in some cases. When it encountered a reference without a death notification request, it would skip looking at the remaining references, and therefore fail to send death notifications for them.

The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the
node release code to a separate function broke death notifications in
some cases. When it encountered a reference without a death
notification request, it would skip looking at the remaining
references, and therefore fail to send death notifications for them.

In commit 7dc19d5aff (convert shrinkers to new count/scan API) the return value to PURGE_ALL_CACHES was dropped, causing -EPERM to always be returned. This patch re-adds the ret assignment, setting it to the the ashmem_shrink_count(), which is the lru_count. (Sorry this was missed in the review!)

I thought that this would be a nice easy class to document fully. Turns out I was very wrong - I will have to research the Linux alarm and timer subsystem one day next week and try again. Here is what I started out with, anyway. It's not much, but it's better than nothing!
