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. # # Reported-by: Joan Bruguera Micó # Reported-by: Jussi Kivilinna # Link: https://bugzilla.kernel.org/show_bug.cgi?id=209971 #
