The patch titled
eCryptfs: kmem_cache objects for multiple keys; init/exit functions
has been removed from the -mm tree. Its filename was
ecryptfs-kmem_cache-objects-for-multiple-keys-init-exit-functions.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: eCryptfs: kmem_cache objects for multiple keys; init/exit functions
From: Michael Halcrow <[EMAIL PROTECTED]>
Introduce kmem_cache objects for handling multiple keys per inode. Add calls
in the module init and exit code to call the key list
initialization/destruction functions.
