Date: Fri, 12 Jan 2018 16:07:31 +0200 From: Pavel Vazharov <freakpv@...il.com> To: mlyle@...e.org, kent.overstreet@...il.com Cc: linux-bcache@...r.kernel.org, linux-kernel@...r.kernel.org, Pavel Vazharov <freakpv@...il.com> Subject: [PATCH] bcache: io.c: Fix check against error_limit in case of io errors The actual sysfs io_error_limit value is left shifted IO_ERROR_SHIFT times before it is stored in the error_limit. This fixes the un-registering of the cache set when the io_errors reach the error_limit value.
