@ -38,6 +38,7 @@ The following `flags` are supported:
* `MS_RDONLY`: Mount the filesystem read-only.
* `MS_REMOUNT`: Remount an already mounted filesystem (see below).
* `MS_WXALLOWED`: Allow W^X protection circumvention for executables on this file system.
* `MS_AXALLOWED`: Allow anonymous executable mappings for executables on this file system.
These flags can be used as a security measure to limit the possible abuses of the newly
mounted file system.
