Subject: [RFC][PATCH 0/4] eCryptfs credentials patches

This patch set modifies the credentials presented by eCryptfs to open
inodes in the lower filesystem. These credentials are initially obtained
through the function prepare_kernel_cred() and may be overridden in order
to identify or restrict actions performed by a specific eCryptfs
filesystem.

More details about how to manage the eCryptfs credentials and how to
measure eCryptfs files with IMA can be found in the file:

'Documentation/filesystems/ecryptfs-security.txt'

Roberto Sassu (4):
  fs: preserve S_IMA inode flag in fsstack_copy_attr_all()
  eCryptfs: introduce per-filesystem credentials
  eCryptfs: override prepared credentials
  eCryptfs: added ima_file_check() call to ecryptfs_init_lower_file()
