Subject: [PATCH 00/10] pstore: Remove filesystem records when backend is unregistered
Date: Wed, 6 May 2020 08:21:04 -0700 [thread overview]
Message-ID: <20200506152114.50375-1-keescook@chromium.org> (raw)
Hi,
This fixes a long-standing problem[1] with pstore where the filesystem
view of backend records was not updated when the backend was unloaded
(in a modular build) through pstore_unregister(). This series is
mostly refactoring and improvements to the various locking semantics
around management of the active backend and the filesystem mount before
ultimately providing the routine to walk the filesystem to remove the
records associated with a given backend.
I'm still doing more build and runtime testing, but I just wanted to get
this posted so I can let other people look at it if they want while the
testing finishes.
Thanks!
-Kees
