Platforms like ARM and KNL can have -core and NUMA setups with things like NUMA nodes with no cores. We need to -handle such cases. This work also greatly simplified the lustre SMP code. - ------------------------------------------------------------------------------- - -https://jira.hpdd.intel.com/browse/LU-9019 - -Replace libcfs time API with standard kernel APIs. Also migrate away from -jiffies. We found jiffies can vary on nodes which can lead to corner cases -that can break the file system due to nodes having inconsistent behavior. -So move to time64_t and ktime_t as much as possible. - -****************************************************************************** -* Proper IB support for ko2iblnd -****************************************************************************** -https://jira.hpdd.intel.com/browse/LU-9179 - -Poor performance for the ko2iblnd driver.

It didn't work with sysfs and it was just ugly so it was removed. -In the process the ability to mass update thousands of clients was lost. This -work restores this in a sane way. - ------------------------------------------------------------------------------- -https://jira.hpdd.intel.com/browse/LU-9091 - -One the major request of users is the ability to pass in parameters into a -sysfs file in various different units. For example we can set max_pages_per_rpc -but this can vary on platforms due to different platform sizes. So you can -set this like max_pages_per_rpc=16MiB. The original code to handle this written -before the string helpers were created so the code doesn't follow that format -but it would be easy to move to. Currently the string helpers does the reverse -of what we need, changing bytes to string. We need to change a string to bytes. - -****************************************************************************** -* Proper user land to kernel space interface for Lustre -* -* https://jira.hpdd.intel.com/browse/LU-9680 -* -****************************************************************************** - -https://jira.hpdd.intel.com/browse/LU-8915 - -Don't use linux list structure as user land arguments for lnet selftest. -This code is pretty poor quality and really needs to be reworked. - ------------------------------------------------------------------------------- - -https://jira.hpdd.intel.com/browse/LU-8834 - -The lustre ioctl LL_IOC_FUTIMES_3 is very generic.

We have many obsolete ioctls. Also the way we do -ioctls can be changed over to netlink. This also has the benefit of working -better with HPC systems that do IO forwarding. Such systems don't like ioctls -very well. - ------------------------------------------------------------------------------- - -https://jira.hpdd.intel.com/browse/LU-9667 - -More cleanups by making our utilities use sysfs instead of ioctls for LNet. -Also it has been requested to move the remaining ioctls to the netlink API. - -****************************************************************************** -* Misc -****************************************************************************** - ------------------------------------------------------------------------------- -https://jira.hpdd.intel.com/browse/LU-9855 - -Clean up obdclass preprocessor code. One of the major eye sores is the various -pointer redirections and macros used by the obdclass. This makes the code very -difficult to understand.
