vfs: Convert cxl to use the new mount API (52418c8f) · Commits · 戴 / test

Convert the cxl filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information. Signed-off-by:
