Subject: [PATCH 107/124] gfapi: add function to set client-pid
|
|
|
17b94a |
|
|
|
17b94a |
This api offers the ability to set the pid of a client to a particular
|
|
|
17b94a |
value, identical to how gluster fuse clients provide the --client-pid
|
|
|
17b94a |
option. This is an internal API to be used by gluster processes only. See
|
|
|
17b94a |
https://lists.gluster.org/pipermail/gluster-devel/2019-March/055925.html
|
|
|
17b94a |
for more details. Currently glfsheal is the only proposed consumer.
