// The mode of the inode. This is exposed to the user in e.g. the result of
// fstat(2).
//
// The permissions bits of the mode are not necessarily respected by the FUSE
// kernel layer unless the file system is mounted with the
// 'default_permissions' option (cf. http://goo.gl/1LxOop).
//
// For example, in the case of mkdir:
//
// * (http://goo.gl/JkdxDI) sys_mkdirat calls inode_permission.
//
// * (...) inode_permission eventually calls do_inode_permission.
//
// * (http://goo.gl/aGCsmZ) calls i_op->permission, which is
// fuse_permission (cf. http://goo.gl/VZ9beH).
//
// * (http://goo.gl/5kqUKO) fuse_permission doesn't do anything at all for
// several code paths if FUSE_DEFAULT_PERMISSIONS is unset. In contrast,
// if that flag *is* set, then it calls generic_permission.
