* staging: lustre: delete the filesystem from the tree.Greg Kroah-Hartman2018-06-051-207/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Lustre filesystem has been in the kernel tree for over 5 years now. While it has been an endless source of enjoyment for new kernel developers learning how to do basic codingstyle cleanups, as well as an semi-entertaining source of bewilderment from the vfs developers any time they have looked into the codebase to try to figure out how to port their latest api changes to this filesystem, it has not really moved forward into the "this is in shape to get out of staging" despite many half-completed attempts. And getting code out of staging is the main goal of that portion of the kernel tree. Code should not stagnate and it feels like having this code in staging is only causing the development cycle of the filesystem to take longer than it should. There is a whole separate out-of-tree copy of this codebase where the developers work on it, and then random changes are thrown over the wall at staging at some later point in time. This dual-tree development model has never worked, and the state of this codebase is proof of that. So, let's just delete the whole mess. Now the lustre developers can go off and work in their out-of-tree codebase and not have to worry about providing valid changelog entries and breaking their patches up into logical pieces. They can take the time they have spend doing those types of housekeeping chores and get the codebase into a much better shape, and it can be submitted for inclusion into the real part of the kernel tree when ready.

* staging: lustre: move stack-check macros to libcfs_debug.hNeilBrown2018-04-231-0/+32
| | | | | | | | | | | | | | CDEBUG_STACK() and CHECK_STACK() are macros to help with debugging, so move them from drivers/staging/lustre/include/linux/libcfs/linux/libcfs.h to drivers/staging/lustre/include/linux/libcfs/libcfs_debug.h This seems a more fitting location, and is a step towards removing linux/libcfs.h and simplifying the include file structure.

* staging: lustre: discard cfs_time_seconds()NeilBrown2018-02-161-2/+2
| | | | | | | | | | | | cfs_time_seconds() converts a number of seconds to the matching number of jiffies. The standard way to do this in Linux is "* HZ". So discard cfs_time_seconds() and use "* HZ" instead.

* staging: lustre: add SPDX identifiers to all lustre filesGreg Kroah-Hartman2017-11-111-0/+1
| | | | | | | | | | | | | | | | | | | | | It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/staging/lustre files files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

* staging/lustre: tracefile: document seconds overflowArnd Bergmann2015-09-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The lustre tracefile has a timestamp defined as __u32 ph_sec; __u64 ph_usec; which seems completely backwards, as the microsecond portion of a time stamp will always fit into a __u32 value, while the second portion will overflow in 2038 or 2106 (in case of unsigned seconds). Changing this would unfortunately change the format in an incompatible way, breaking all existing user space tools that access the data. This uses ktime_get_real_ts64() to replace the insufficient do_gettimeofday() and then truncates the seconds portion to an u32 type, along with comments to explain the result. A possible alternative would be the use of ktime_get_ts64() to read a monotonic timestamp that never overflows, but this would trigger a check in user space 'hdr->ph_sec < (1 << 30)' that attempts to ensure that the values are within a reasonable range.
