Move the function declartions that are used only by kernel space to libcfs.h This makes libcfs_ioctl.h a offical uapi header now. Move large inline functions out of libcfs_ioctl.h to the source file linux-module.c belonging to libcfs. This code is only used by the core of libcfs and such inline functions don't belong in a uapi header file. Signed-off-by:

No reason to go through the cfs_psdev_ops abstract to call libcfs_ioctl. Just call libcfs_ioctl directly. Signed-off-by:

With struct libcfs_device_userstate gone we can remove the remaining code of libcfs_psdev_ops.p_[open|close] as well as the libcfs_psdev_[open|release] functions. Signed-off-by:

A few pieces still exist for the IOC_LIBCFS_PANIC ioctl. Remove these last bits to prevent old tools from using them. The latest lustre utilities no longer use this ioctl. Signed-off-by:

Move all the libcfs_ioctl_handler code from libcfs_ioctl.h to libcfs.h. The header libcfs_ioctl.h is a uapi header so their is no reason to keep kernel internals in that header. Signed-off-by:

This is apart of the cleanup of libcfs_ioctl* code. In this part we turn libcfs_ioctl_handle into libcfs_ioctl since libcfs_ioctl is now a skeleton function. Signed-off-by:

The size of LNET_MAX_IOCTL_BUF_LEN restricts the size of libcfs ioctl to the maximum needs of the LNet layer. Since libcfs also handles things like debugging we might need to let user land pass more data to or from the kernel than what is possible Signed-off-by:

Commit 4671a0266 change the parameter of the second parameter of cfs_precpt_alloc() from a sizeof type to sizeof type *pointer. This was incorrect in this case and it caused a crash when the LNet layer was brought up in my testing. The reason is cfs_precpt_alloc() creates an array of items where the arrays size is equal to the number of CPTs that exist. Changing to type *pointer only had cfs_precpt_alloc() create an array of pointers instead of an array of actual data structures. This patch reverse this change and adds comments to explain what cfs_precpt_alloc() is actually doing to avoid potential issues like this again. Changelog: v1) Simple revert of the original patch v2) Added in comments to explain why cfs_precpt_alloc() has the arguments it uses.

Replace calls to request_mem_region and ioremap with a direct call to devm_ioremap_resource instead and modify error handling. Move the call to platform_get_resource adjacent to the call to devm_ioremap_resource to make the connection between them more clear. Also remove unnecessary labels, variable initialisations and release_mem_region iounmap from probe and remove functions. Signed-off-by:

devm_clk_get allocated resources get released when a driver detaches. Replace clk_get with devm_clk_get and remove corresponding data releasing function clk_put from probe and remove functions of a platform device. Also remove an unnecessary label. This change was made with the help of the following Coccinelle semantic patch: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e; @@ probefn(struct platform_device *pdev, ...) { ... e = - clk_get + devm_clk_get (...); ... ?- clk_put(...); ... } @remove depends on prb@ identifier platform.removefn; @@ removefn(...) { ... ?- clk_put(...); ... } Signed-off-by: -
