2017-06-21CIFS: Fix some return values in case of error in 'crypt_message'Christophe Jaillet
'rc' is known to be 0 at this point. So if 'init_sg' or 'kzalloc' fails, we should return -ENOMEM instead. Also remove a useless 'rc' in a debug message as it is meaningless here.

2017-06-20blk-mq: Warn when attempting to run a hardware queue that is not mappedBart Van Assche
A queue must be frozen while the mapped state of a hardware queue is changed. Additionally, any change of the mapped state is followed by a call to blk_mq_map_swqueue() (see also blk_mq_init_allocated_queue() and blk_mq_update_nr_hw_queues()). Since blk_mq_map_swqueue() does not map any unmapped hardware queue onto any software queue, no attempt will be made to run an unmapped hardware queue. Hence issue a warning upon attempts to run an unmapped hardware queue.

2017-06-20block: Document what queue type each function is intended forBart Van Assche
Some functions in block/blk-core.c must only be used on blk-sq queues while others are safe to use against any queue type. Document which functions are intended for blk-sq queues and issue a warning if the blk-sq API is misused. This does not only help block driver authors but will also make it easier to remove the blk-sq code once that code is declared obsolete.

2017-06-20blk-mq: Initialize .rq_flags in blk_mq_rq_ctx_init()Bart Van Assche
Initialization of blk-mq requests is a bit weird: blk_mq_rq_ctx_init() is called after a value has been assigned to .rq_flags and .rq_flags is initialized in __blk_mq_finish_request(). Initialize .rq_flags in blk_mq_rq_ctx_init() instead of relying on __blk_mq_finish_request(). Moving the initialization of .rq_flags is fine because all changes and tests of .rq_flags occur between blk_get_request() and finishing a request.

2017-06-20block: Make most scsi_req_init() calls implicitBart Van Assche
Instead of explicitly calling scsi_req_init() after blk_get_request(), call that function from inside blk_get_request(). Add an .initialize_rq_fn() callback function to the block drivers that need it. Merge the IDE .init_rq_fn() function into .initialize_rq_fn() because it is too small to keep it as a separate function. Keep the scsi_req_init() call in ide_prep_sense() because it follows a blk_rq_init() call.

2017-06-20block: Introduce request_queue.initialize_rq_fn()Bart Van Assche
Several block drivers need to initialize the driver-private request data after having called blk_get_request() and before .prep_rq_fn() is called, e.g. when submitting a REQ_OP_SCSI_* request. Avoid that that initialization code has to be repeated after every blk_get_request() call by adding new callback functions to struct request_queue and to struct blk_mq_ops.

In the actual set timer implementation the timespec is converted to a scalar nanoseconds value. If the tv_sec part of the time spec is large enough the conversion to nanoseconds (sec * NSEC_PER_SEC) overflows 64bit.

2017-06-20perf tools: Remove unused _ALL_SOURCE defineArnaldo Carvalho de Melo
Curious as to what this was for I looked at /usr/include/ and only some python headers define this, and it ends up being to enable "extensions" on some old OSes: /* Enable extensions on AIX 3, Interix */ I guess we can remove this one safely.

2017-06-20perf tools: Do parameter validation earlier on fetch_kernel_version()Arnaldo Carvalho de Melo
While trying to reduce util.[ch] I noticed that fetch_kernel_version() and fetch_ubuntu_kernel_version() do lots of operations only to check if they are needed, i.e. it checks if the pointer where to return the kernel version is NULL only after obtaining the kernel version from /proc/version_signature or by parsing the results from uname(). Do it earlier not to confuse people reading this code in the future :-) Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-i94qwyekk4tzbu0b9ce1r1mz@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2017-06-20perf evsel: Adopt find_process()Arnaldo Carvalho de Melo
And make it static, nobody else uses it, if we ever need it in more places we can carve a new source file for process related methods, for now lets reduce util.{c,h} a tad more.

2017-06-20KVM: MIPS: Fix maybe-uninitialized build failureJames Cowgill
This commit fixes a "maybe-uninitialized" build failure in arch/mips/kvm/tlb.c when KVM, DYNAMIC_DEBUG and JUMP_LABEL are all enabled. The failure is: In file included from ./include/linux/printk.h:329:0, from ./include/linux/kernel.h:13, from ./include/asm-generic/bug.h:15, from ./arch/mips/include/asm/bug.h:41, from ./include/linux/bug.h:4, from ./include/linux/thread_info.h:11, from ./include/asm-generic/current.h:4, from ./arch/mips/include/generated/asm/current.h:1, from ./include/linux/sched.h:11, from arch/mips/kvm/tlb.c:13: arch/mips/kvm/tlb.c: In function ‘kvm_mips_host_tlb_inv’: ./include/linux/dynamic_debug.h:126:3: error: ‘idx_kernel’ may be used uninitialized in this function [-Werror=maybe-uninitialized] __dynamic_pr_debug(&descriptor, pr_fmt(fmt), \ ^~~~~~~~~~~~~~~~~~ arch/mips/kvm/tlb.c:169:16: note: ‘idx_kernel’ was declared here int idx_user, idx_kernel; ^~~~~~~~~~ There is a similar error relating to "idx_user". Both errors were observed with GCC 6. As far as I can tell, it is impossible for either idx_user or idx_kernel to be uninitialized when they are later read in the calls to kvm_debug, but to satisfy the compiler, add zero initializers to both variables.
