From 7578d5cd1e0fe71736970372fcf96341d69f2234 Mon Sep 17 00:00:00 2001 From: Gioh Kim Date: Thu, 26 Nov 2020 11:47:19 +0100 Subject: [PATCH] Documentation/ABI/rnbd-clt: session name is appended to the device path When mapping a device, /sys/devices/virtual/rnbd-client/ctl/devices/ was created. But we found out that it had a problem when mapping the same file on different servers. So we append the session name after the device_id as below. /sys/devices/virtual/rnbd-client/ctl/devices/@ Signed-off-by: Gioh Kim Signed-off-by: Jack Wang Signed-off-by: Jens Axboe --- Documentation/ABI/testing/sysfs-class-rnbd-client | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/Documentation/ABI/testing/sysfs-class-rnbd-client b/Documentation/ABI/testing/sysfs-class-rnbd-client index ca3267b..2aa05b3 100644 --- a/Documentation/ABI/testing/sysfs-class-rnbd-client +++ b/Documentation/ABI/testing/sysfs-class-rnbd-client @@ -95,12 +95,12 @@ Description: Expected format is the following:: --------------------------------- After mapping, the device file can be found by: - o The symlink /sys/class/rnbd-client/ctl/devices/ + o The symlink /sys/class/rnbd-client/ctl/devices/@ points to /sys/block/.
