tools/test/nvdimm: Fix out of tree build

2020-04-29T14:32:59+00:00

[ Upstream commit 1f776799628139d0da47e710ad86eb58d987ff66 ] Out of tree build using make M=tools/test/nvdimm O=/tmp/build -C /tmp/build fails with the following error make: Entering directory '/tmp/build' CC [M] tools/testing/nvdimm/test/nfit.o linux/tools/testing/nvdimm/test/nfit.c:19:10: fatal error: nd-core.h: No such file or directory 19 | #include | ^~~~~~~~~~~ compilation terminated. That is because the kbuild file uses $(src) which points to tools/testing/nvdimm, $(srctree) correctly points to root of the linux source tree.

tools/testing/nvdimm: Fix compilation failure without CONFIG_DEV_DAX_PMEM_COMPAT

2020-04-29T14:32:57+00:00

[ Upstream commit c0e71d602053e4e7637e4bc7d0bc9603ea77a33f ] When a kernel is configured without CONFIG_DEV_DAX_PMEM_COMPAT, the compilation of tools/testing/nvdimm fails with: Building modules, stage 2. MODPOST 11 modules ERROR: "dax_pmem_compat_test" [tools/testing/nvdimm/test/nfit_test.ko] undefined! Fix the problem by calling dax_pmem_compat_test() only if the kernel has the required functionality.

libnvdimm/nfit_test: Fix acpi_handle redefinition

2019-09-24T17:24:18+00:00

After commit 62974fc389b3 ("libnvdimm: Enable unit test infrastructure compile checks"), clang warns: In file included from ../drivers/nvdimm/../../tools/testing/nvdimm/test/iomap.c:15: ../drivers/nvdimm/../../tools/testing/nvdimm/test/nfit_test.h:206:15: warning: redefinition of typedef 'acpi_handle' is a C11 feature [-Wtypedef-redefinition] typedef void *acpi_handle; ^ ../include/acpi/actypes.h:424:15: note: previous definition is here typedef void *acpi_handle; /* Actually a ptr to a NS Node */ ^ 1 warning generated. The include chain: iomap.c -> linux/acpi.h -> acpi/acpi.h -> acpi/actypes.h nfit_test.h Avoid this by including linux/acpi.h in nfit_test.h, which allows us to remove both the typedef and the forward declaration of acpi_object.

memremap: remove the dev field in struct dev_pagemap

2019-08-20T12:41:35+00:00

The dev field in struct dev_pagemap is only used to print dev_name in two places, which are at best nice to have. Just remove the field and thus the name in those two messages.

memremap: provide an optional internal refcount in struct dev_pagemap

2019-07-02T17:32:44+00:00

Provide an internal refcounting logic if no ->ref field is provided in the pagemap passed into devm_memremap_pages so that callers don't have to reinvent it poorly.

Passing the actual typed structure leads to more understandable code vs just passing the ref member.

memremap: move dev_pagemap callbacks into a separate structure

2019-07-02T17:32:44+00:00

The dev_pagemap is a growing too many callbacks. Move them into a separate ops structure so that they are not duplicated for multiple instances, and an attacker can't easily overwrite them.
