[PATCH v3] dma-buf: cleanup dma_buf_export() to make it easily extensible

by Sumit Semwal

At present, dma_buf_export() takes a series of parameters, which makes it difficult to add any new parameters for exporters, if required. Make it simpler by moving all these parameters into a struct, and pass the struct * as parameter to dma_buf_export(). While at it, unite dma_buf_export_named() with dma_buf_export(), and change all callers accordingly. Signed-off-by: Sumit Semwal <sumit.semwal(a)linaro.org> --- v3: Daniel Thompson caught the C99 warning issue w/ using {0}; using {.exp_name = xxx} instead. v2: add macro to zero out local struct, and fill KBUILD_MODNAME by default drivers/dma-buf/dma-buf.c | 47 +++++++++++++------------- drivers/gpu/drm/armada/armada_gem.c | 10 ++++-- drivers/gpu/drm/drm_prime.c | 12 ++++--- drivers/gpu/drm/exynos/exynos_drm_dmabuf.c | 9 +++-- drivers/gpu/drm/i915/i915_gem_dmabuf.c | 10 ++++-- drivers/gpu/drm/omapdrm/omap_gem_dmabuf.c | 9 ++++- drivers/gpu/drm/tegra/gem.c | 10 ++++-- drivers/gpu/drm/ttm/ttm_object.c | 9 +++-- drivers/gpu/drm/udl/udl_dmabuf.c | 9 ++++- drivers/media/v4l2-core/videobuf2-dma-contig.c | 8 ++++- drivers/media/v4l2-core/videobuf2-dma-sg.c | 8 ++++- drivers/media/v4l2-core/videobuf2-vmalloc.c | 8 ++++- drivers/staging/android/ion/ion.c | 9 +++-- include/linux/dma-buf.h | 34 +++++++++++++++---- 14 files changed, 142 insertions(+), 50 deletions(-) diff --git a/drivers/dma-buf/dma-buf.c b/drivers/dma-buf/dma-buf.c index 5be225c2ba98..6d3df3dd9310 100644 --- a/drivers/dma-buf/dma-buf.c +++ b/drivers/dma-buf/dma-buf.c @@ -265,7 +265,7 @@ static inline int is_dma_buf_file(struct file *file) } /** - * dma_buf_export_named - Creates a new dma_buf, and associates an anon file + * dma_buf_export - Creates a new dma_buf, and associates an anon file * with this buffer, so it can be exported. * Also connect the allocator specific data and ops to the buffer. * Additionally, provide a name string for exporter; useful in debugging. @@ -277,31 +277,32 @@ static inline int is_dma_buf_file(struct file *file) * @exp_name: [in] name of the exporting module - useful for debugging. * @resv: [in] reservation-object, NULL to allocate default one. * + * All the above info comes from struct dma_buf_export_info. + * * Returns, on success, a newly created dma_buf object, which wraps the * supplied private data and operations for dma_buf_ops.

[PATCH] cpufreq: Set cpufreq_cpu_data to NULL before putting kobject

by Viresh Kumar

cpufreq_cpu_data is protected by cpufreq_driver_lock and one of the instances has missed this. And as a result we get this: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 4 at include/linux/kref.h:47 kobject_get+0x41/0x50() Modules linked in: acpi_cpufreq(+) nfsd auth_rpcgss nfs_acl lockd grace sunrpc xfs libcrc32c sd_mod ixgbe igb mdio ahci hwmon ...

But the race happens when another thread puts the kobject first and updates cpufreq_cpu_data later and that too without these locks. And so the first thread gets a valid policy structure and before it does kobject_get() on it, the second one does kobject_put(). And so this WARN(). Fix this by setting cpufreq_cpu_data to NULL before putting the kobject and that too under locks.
