#     proc mountinfo: make splice available again
#     
#     Since commit 36e2c7421f02 ("fs: don't allow splice read/write without
#     explicit ops") we've required that file operation structures explicitly
#     enable splice support, rather than falling back to the default handlers.
#     
#     Most /proc files use the indirect 'struct proc_ops' to describe their
#     file operations, and were fixed up to support splice earlier in commits
#     40be821d627c..b24c30c67863, but the mountinfo files interact with the
#     VFS directly using their own 'struct file_operations' and got missed as
#     a result.
#     
#     This adds the necessary support for splice to work for /proc/*/mountinfo
#     and friends.
