Hi, this is a revised patch series for another attempt to address the potential deadlocks via kill_fasync() calls that have been reported by syzbot for long time. Only a missing linux/fs.h inclusion was added from v1 series[1]. Instead of the previous series to drop the async handler[2], this tries to defer the kill_fasync() call. A few new common helpers are introduced at first, then the actual usages are replaced in the following patches. The patches passed the quick tests with alsa-lib test cases.
Thank you for your work. The code looks good (I would only move schedule_work() call outside the spin lock context - commented in the patch thread).
