Subject: [PATCH v3 34/47] 9p: adapt to breakup of struct file_lock
Date: Wed, 31 Jan 2024 18:02:15 -0500 [thread overview]
Message-ID: <20240131-flsplit-v3-34-c6129007ee8d@kernel.org> (raw)
In-Reply-To: <20240131-flsplit-v3-0-c6129007ee8d@kernel.org>
Most of the existing APIs have remained the same, but subsystems that
access file_lock fields directly need to reach into struct
file_lock_core now.
