The patch titled
ecryptfs: fix error handling
has been removed from the -mm tree. Its filename was
ecryptfs-fix-error-handling.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ecryptfs: fix error handling
From: Michael Halcrow <mhalcrow@xxxxxxxxxx>
The error paths and the module exit code need work. sysfs
unregistration is not the right place to tear down the crypto
subsystem, and the code to undo subsystem initializations on various
error paths is unnecessarily duplicated. This patch addresses those
issues.
