2016-03-10staging: lustre: make lustre dependent on LNetJames Simmons
In the case of lustre routers you only need a functioning LNet stack. Especially since often the routers are very light weight and want to avoid any addition software that would create additional pressures on the system.

A few errors exist for the Kconfig option LNET_MAX_PAYLOAD. First mistake is the default size is 1MB not 2MB as it is shown to the person configuring the kernel.

2016-03-10staging: lustre: move libcfs to lnet layerJames Simmons
The lustre file system has a layered architecture with libcfs as the lowest layer and LNet layered on top. Then on top of LNet we run the lustre client. This patch moves the libcfs module code out of lustre into the lnet tree. This fits into the long term goal of eventually merging libcfs into LNet.

2016-03-07staging: lustre: make LNet use lprocfs_call_handlerJames Simmons
Sometime ago a patch was submitted to duplicate the proc_call_handler code in the LNet layer. This was due to the thinking libcfs was not used by the LNet layer.

2016-03-07staging: lustre: Correct missing newlineJames Nunez
Several error messages are missing newline characters at the end of the message. Newlines are added where necessary and other minor corrections; no punctuation at the end of an error message, add a return code to the end of error messages, device name at the beginning, etc. There are just a couple of places where newlines are removed and this is only in LDLM_DEBUG_NOLOCK. The definition of LDLM_DEBUG_NOLOCK already has a newline in it and resulted in double newlines printed.

2016-03-05isdn: i4l: move active-isdn drivers to stagingArnd Bergmann
The icn, act2000 and pcbit drivers are all for very old hardware, and it is highly unlikely that anyone is actually still using them on modern kernels, if at all. All three drivers apparently are for hardware that predates PCI being the common connector, as they are ISA-only and active PCI ISDN cards were widely available in the 1990s. Looking through the git logs, it I cannot find any indication of a patch to any of these drivers that has been tested on real hardware, only cleanups or global API changes.

2016-03-05isdn: icn: remove a #warningArnd Bergmann
The icn driver currently produces an unconditional #warning whenever we build it, introduced by Karsten Keil back in 2003: #warning TODO test headroom or use skb->nb to flag ACK Karsten's original commit (from BitKeeper) contains this description: - here are lot of bugs left, so ISDN is not stable yet but I think it's really time to fix it, even if it need some cycles to get it right (normally I'm only send patches if it works 100% for me). - I add some additional #warnings to address places which need fixing (I hope that some of the other ISDN developer jump in) Apparently this has not happened, and it is unlikely that it ever will, given that the driver doesn't seem to work. No substantial bug fixes other than janitorial cleanups have happened in the driver since then, and I see no indication that anyone who patched it had the hardware. We should probably either remove the driver, or remove all of i4l, but for now, this shuts up the distracting #warning by turning it into a comment.

Replace the use of the `BIT` macro with hexadecimal constants of the same value. The `BIT` macro replaced expressions of the form `(1 << N)` in this file originally, but reverting back to that form would encourage patches changing them back to use the `BIT` macro.

Since there are multiple work items per udev but different udevs do not need to be ordered, increase of concurrency level by switching to system_wq should not break anything. cancel_work_sync() is used to ensure that work is not pending or executing on any CPU. Lastly, since all devices are suspended, which shutdowns the work items before the driver can be unregistered, it is guaranteed that no work item is pending or executing by the time exit path runs.

2016-03-05staging: lustre: handle complex strings in cfs_str2num_checkJames Simmons
Originally the function cfs_str2num_check used simple_strtoul but has been updated to kstrtoul. The string passed into cfs_str2num_check can be a very complex, for example we could have 10.37.202.[59-61]. When simple_strtoul was used the first number until we hit a non-digit character could be extracted but testing showed that kstrtoul will not return any value if it detects any non-digit character. Because of this change in behavior a different approach is needed to handle these types of complex strings. The use of sscanf was investigated to see if it could be used to extract numbers from the passed in string but unlike its glibc counterpart the kernel version also just reported a error with no results if a non-digit value in the string was encountered. Another possible approach would be to use __parse_int directly but that class of functions is not exported by the kernel. So the approach in this patch is to scan the string passed in for the first non-digit character and replace that character with a '\0' so kstrtoul can be used. Once completed the original character is restored. We also restore a original behavior that was removed to return 0 when we encounter any non digit character before the nob count.
