The patch titled
revoke: misc fixes
has been removed from the -mm tree. Its filename was
revoke-core-code-misc-fixes.patch
This patch was dropped because it was folded into revoke-core-code.patch
------------------------------------------------------
Subject: revoke: misc fixes
From: Pekka Enberg <[EMAIL PROTECTED]>
This is a rollup patch of the following fixes to address some of Andrew's
review comments:
- Fix return value type of system calls to long
- Add comment for vma->vm_flag barrier
- No need for GFP_NOFS for inode allocation, use GFP_KERNEL instead
- Remove unnecessary line break before EXPORT_SYMBOL
