#define V9FS_ACCESS_ANY

Value:

(V9FS_ACCESS_SINGLE | \
             V9FS_ACCESS_USER |   \
             V9FS_ACCESS_CLIENT)

enum p9_session_flags - option flags for each 9P session : whether or not to use 9P2000.u extensions : whether or not to use 9P2000.l extensions : only the mounting user can access the hierarchy : a new attach will be issued for every user (default) : Just like user, but access check is performed on client. : use a single attach for all users : bit mask of different ACCESS options : POSIX ACLs are enforced

Session flags reflect options selected by users at mount time
