H A D | mount.h | 7d6fec45 Wed Nov 23 11:14:10 CST 2011 Al Viro <viro@zeniv.linux.org.uk> vfs: start hiding vfsmount guts series
Almost all fields of struct vfsmount are used only by core VFS (and a fairly small part of it, at that). The plan: embed struct vfsmount into struct mount, making the latter visible only to core parts of VFS. Then move fields from vfsmount to mount, eventually leaving only mnt_root/mnt_sb/mnt_flags in struct vfsmount. Filesystem code still gets pointers to struct vfsmount and remains unchanged; all such pointers go to struct vfsmount embedded into the instances of struct mount allocated by fs/namespace.c. When fs/namespace.c et.al. get a pointer to vfsmount, they turn it into pointer to mount (using container_of) and work with that.
This is the first part of series; struct mount is introduced, allocation switched to using it.
