Subject: [PATCH 1/2] pidfd_create(): remove static qualifier and declare pidfd_create() in linux/pid.h
Date: Fri, 16 Apr 2021 09:22:09 +1000 [thread overview]
Message-ID: <14a09477f0b2d62a424b44e0a1f12f32ae3409bb.1618527437.git.repnop@google.com> (raw)
In-Reply-To: <cover.1618527437.git.repnop@google.com>
With the idea to have fanotify(7) return pidfds within a `struct
fanotify_event_metadata`, pidfd_create()'s scope is to increased so
that it can be called from other subsystems within the Linux
kernel. The current `static` qualifier from its definition is to be
removed and a new function declaration for pidfd_create() is to be
added to the linux/pid.h header file.
