[PATCH 3/3] staging:lustre: cleanup libcfs lock handling

by James Simmons

Previously with libcfs being built for user land and kernel space wrappers were created to transparently handle locking. Now that user land support has been removed we delete all those locking wrappers with this patch. Many of those changes landed upstream but some nice cleanups still remain that are pushed in this patch.

[PATCH] staging: lustre: remove unused variable warning

by Arnd Bergmann

A recent patch to simplify the lustre large memory allocation causes new warnings as an unintended side-effect: lustre/lov/lov_request.c: In function 'lov_finish_set': lustre/lov/lov_request.c:78:7: warning: unused variable 'len' [-Wunused-variable] int len = set->set_oabufs * sizeof(*set->set_pga); ^ lustre/obdclass/acl.c: In function 'lustre_ext_acl_xattr_reduce_space': lustre/obdclass/acl.c:123:6: warning: unused variable 'old_size' [-Wunused-variable] int old_size = CFS_ACL_XATTR_SIZE(old_count, ext_acl_xattr); ^ The reason is that the 'size' argument to OBD_FREE_LARGE() is never needed, which was previously hidden by the extra abstractions. This avoids the warnings by adding a cast to void, to tell the compiler that the argument is intentionally unused. A better fix is probably to remove the entire set of allocation macros and open-code the normal kernel interface calls.

lustre_dlm_flags.h GPLv3 license clarification

by George G. Davis

Greetings, Resending this using the correct version of get_maintainers.pl. As recommended in the thread "SPDX-License-Identifier” [1], I would like to followup with the maintainers of the file drivers/staging/lustre/lustre/include/lustre_dlm_flags.h regarding the GPLv3 license statement contained in that file [2]. Is there an GPLv3 exception clause which can be applied for this file similar to the bison exception clause or is this file licensed only under GPLv3 only in which case it would appear to be incompatible with the Linux kernel license [3]? TIA! — Regards, George [1] https://lkml.org/lkml/2015/2/5/65 [2] https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/driv...
