[$] Handling filesystem interruptibility

David Howells wanted to discuss changing the way filesystem code handlesthe ability to interrupt or kill operations, in order to fix somelongstanding problems with network (and other) filesystems, in a session atthe 2024 LinuxStorage, Filesystem, Memory Management, and BPF Summit. As noted inhis sessionproposal, some filesystems may be expecting to not be interruptible,but are calling code can take locks and mutexes that are interruptible (orkillable), which are effectivelychanging the state of the task incorrectly.He would like to find a solution for that problem.
