Merge tag 'ecryptfs-3.19-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs
Pull eCryptfs fixes from Tyler Hicks:
"Fixes for filename decryption and encrypted view plus a cleanup
- The filename decryption routines were, at times, writing a zero
byte one character past the end of the filename buffer
- The encrypted view feature attempted, and failed, to roll its own
form of enforcing a read-only mount instead of letting the VFS
enforce it"
* tag 'ecryptfs-3.19-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs:
eCryptfs: Remove buggy and unnecessary write in file name decode routine
eCryptfs: Remove unnecessary casts when parsing packet lengths
eCryptfs: Force RO mount when encrypted view is enabled
