Subject: [PATCH 06/22] shmem: export shmem_kernel_file_setup
Date: Mon, 19 Feb 2024 07:27:14 +0100	[thread overview]
Message-ID: <20240219062730.3031391-7-hch@lst.de> (raw)
In-Reply-To: <20240219062730.3031391-1-hch@lst.de>

XFS wants to use this for it's internal in-memory data structures and
currently duplicates the functionality.  Export shmem_kernel_file_setup
to allow XFS to switch over to using the proper kernel API.
