Subject: [PATCH v2 0/2] Drivers: hv: vmbus: Fix sysfs functions that display monitor id and page data
Date: Tue, 19 Feb 2019 00:37:54 -0500	[thread overview]
Message-ID: <cover.1550549612.git.kimbrownkd@gmail.com> (raw)
In-Reply-To: <cover.1549619051.git.kimbrownkd@gmail.com>

Some of the monitor id and monitor page data sysfs files display
incorrect data. This patchset provides the following changes:

1) Change the monitor_pages index in server_monitor_pending_show() to
'0', which is the correct index for the server.

2) If monitor pages are not allocated to a channel, return -EINVAL when
the channel's monitor id and monitor page data sysfs files are opened.
The data that is currently shown in sysfs is incorrect.

Changes in v2:

Patch 1: "Change server monitor_pages index to 0"
 - Added the "Acked-by" line received for v1.

Patch 2: "Return -EINVAL if monitor_allocated not set"
 - Changed the return value for cases where monitor_allocated is not set
   to "-EINVAL" as suggested by S. Hemminger.
 - Updated the commit message to provide more details about the monitor
   page mechanism as suggested by S. Hemminger.
 - Updated the sysfs documentation to describe the new return value.
