In preparation for an upcoming patch which adds support for SUSE guest conversions, it makes sense to have an intermediate steps that changes the RedHat.pm converter into a more generic Linux converter. The SUSE changes will then be limited in scope to only what is required for SUSE support. This series of patches accomplishes the following: - Renames RedHat.pm to Linux.pm - Modifies Linux.pm

This series tries to access virtqueue metadata through kernel virtual address instead of copy_user() friends since they had too much overheads like checks, spec barriers or even hardware feature toggling. This is done through setup kernel address through vmap() and resigter MMU notifier for invalidation. Test shows about 24% improvement on TX PPS. TCP_STREAM doesn't see obvious improvement.

v5: - Break the btrfs patch out as a separate patch to be processed independently. - Update the commit log of patch 1 to make it less scary. - Add a kzfree backward compatibility macro in patch 2. v4: - Break out the memzero_explicit() change as suggested by Dan Carpenter so that it can be backported to stable. - Drop the "crypto: Remove unnecessary

v4: - Break out the memzero_explicit() change as suggested by Dan Carpenter so that it can be backported to stable. - Drop the "crypto: Remove unnecessary memzero_explicit()" patch for now as there can be a bit more discussion on what is best. It will be introduced as a separate patch later on after this one is merged. This patchset makes a global rename of the kzfree()

This patchset makes a global rename of the kzfree() to kfree_sensitive() to highlight the fact buffer clearing is only needed if the data objects contain sensitive information like encrpytion key. The fact that kzfree() uses memset() to do the clearing isn't totally safe either as compiler may compile out the clearing in their optimizer. Instead, the new kfree_sensitive() uses

Hi all - The following 9 patches add more error handling to the btrfs code: - Add btrfs_panic - Catch locking failures in {set,clear}_extent_bit - Push up set_extent_bit errors to callers - Push up lock_extent errors to callers - Push up clear_extent_bit errors to callers - Push up unlock_extent errors to callers - Make pin_down_extent return void - Push up btrfs_pin_extent errors to
