From 21df134f4cb1c1e05eb89992b71573843df62b27 Mon Sep 17 00:00:00 2001 From: sanjeevbagewadi Date: Fri, 11 Aug 2017 04:23:40 +0530 Subject: [PATCH] zio_dva_throttle_done() should allow zinjected ZIO If fault injection is enabled, the ZIO_FLAG_IO_RETRY could be set by zio_handle_device_injection() to generate the FMA events and update stats. Hence, ignore the flag and process such zios. A better fix would be to add another flag in the zio_t to indicate that the zio is failed because of a zinject rule. However, considering the fact that we do this in debug bits, we could do with the crude check using the global flag zio_injection_enabled which is set to 1 when zinject records are added.
