Subject: [PATCH 0/2] unix: Show number of scm files in fdinfo
Date: Thu, 07 Nov 2019 15:14:15 +0300	[thread overview]
Message-ID: <157312863230.4594.18421480718399996953.stgit@localhost.localdomain> (raw)

Unix sockets like a block box. You never know what is pending there:
there may be a file descriptor holding a mount or a block device,
or there may be whole universes with namespaces, sockets with receive
queues full of sockets etc.

The patchset makes number of pending scm files be visible in fdinfo.
This may be useful to determine, that socket should be investigated
or which task should be killed to put reference counter on a resourse.
