Subject: [PATCH 0/2] Add support for enhanced atomic operations
Date: Mon, 01 Feb 2010 17:59:16 +0200 [thread overview]
Message-ID: <4B66FA54.6030408@dev.mellanox.co.il> (raw)
Hi Roland,
This patchset adds support for the following enhanced atomic operations:
- Masked atomic compare and swap
- Masked atomic fetch and add
These operations enable using a smaller amount of memory when using multiple locks
by using portions of a 64 bit value in an atomic operation.
