[PATCH 0/3] LSM: Multiple LSM mount options

[Casey Schaufler]

Linux Security Module (LSM) that support mount options, currently SELinux
and Smack, allocate their own data for those options. This patch set
moves the handling of mount option data out of the individual LSMs and
into the LSM infrastructure. This allows for multiple LSMs to support
mount options at the same time.

Based on patches Paul Moore's LSM initialization patchset.
