From 0b9bf3812ad1f0d937584e300826285694f53e2b Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 25 Apr 2019 14:26:50 +0100 Subject: [PATCH] afs: Split wait from afs_make_call() Split the call to afs_wait_for_call_to_complete() from afs_make_call() to make it easier to handle asynchronous calls and to make it easier to convert a synchronous call to an asynchronous one in future, for instance when someone tries to interrupt an operation by pressing Ctrl-C.
