From 220946c9018de74b952446e3a4dff1bfd4cbf310 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 6 Jan 2006 00:20:27 -0800 Subject: [PATCH] [PATCH] md: make sure read error on last working drive of raid1 actually returns failure We are inadvertently setting the R1BIO_Uptodate bit on read errors when we decide not to try correcting (because there are no other working devices). This means that the read error is reported to the client as success.
