From 8ec41c4265714255d5a138f8b538faf3583dcff6 Mon Sep 17 00:00:00 2001 From: John Snow Date: Mon, 29 Jul 2019 18:36:05 -0400 Subject: [PATCH] Revert "ide/ahci: Check for -ECANCELED in aio callbacks" This reverts commit 0d910cfeaf2076b116b4517166d5deb0fea76394. It's not correct to just ignore an error code in a callback; we need to handle that error and possible report failure to the guest so that they don't wait indefinitely for an operation that will now never finish. This ought to help cases reported by Nutanix where iSCSI returns a legitimate -ECANCELED for certain operations which should be propagated normally.
