From 10f2c8db915df14102e3f4d9efcfce372c90707a Mon Sep 17 00:00:00 2001 From: Nicolas Lacasse Date: Fri, 27 Mar 2020 16:53:28 -0700 Subject: Add FilesystemType.Name method, and FilesystemType field to Filesystem struct. Both have analogues in Linux: * struct file_system_type has a char *name field. * struct super_block keeps a pointer to the file_system_type. These fields are necessary to support the `filesystem type` field in /proc/[pid]/mountinfo.
