2017-04-18orangefs: fix buffer size mis-match between kernel space and user space.Mike Marshall
commit eb68d0324dc4d88ab0d6159bdcd98c247a3a8954 upstream. The deamon through which the kernel module communicates with the userspace part of Orangefs, the "client-core", sends initialization data to the kernel module with ioctl. The initialization data was built by the client-core in a 2k buffer and copy_from_user'd into a 1k buffer in the kernel module. When more than 1k of initialization data needed to be sent, some was lost, reducing the usability of the control by which debug levels are set. This patch sets the kernel side buffer to 2K to match the userspace side...

2016-08-12orangefs: add features opMartin Brandenburg
This is a new userspace operation, which will be done if the client-core version is greater than or equal to 2.9.6. This will provide a way to implement optional features and to determine which features are supported by the client-core. If the client-core version is older than 2.9.6, no optional features are supported and the op will not be done. The intent is to allow protocol extensions without relying on the client-core's current behavior of ignoring what it doesn't understand. Signed-off-by: Martin Brandenburg <martin@omnibond.com>
2016-08-08orangefs: rename remaining bits of mmap readahead cacheMartin Brandenburg
This has been dormant code for many years. Parts of it were removed from the OrangeFS kernel code when it went into mainline. These bits were missed. Now the readahead cache has been resurrected in the OrangeFS userspace portions. It was renamed there, since it doesn't really have anything to do with mmap specifically, so it will be renamed here.
