  "message": "[PATCH] bitmap: parse input from kernel and user buffers\n\nlib/bitmap.c:bitmap_parse() is a library function that received as input a\nuser buffer.  This seemed to have originated from the way the write_proc\nfunction of the /proc filesystem operates.\n\nThis has been reworked to not use kmalloc and eliminates a lot of\nget_user() overhead by performing one access_ok before using __get_user().\n\nWe need to test if we are in kernel or user space (is_user) and access the\nbuffer differently.  We cannot use __get_user() to access kernel addresses\nin all cases, for example in architectures with separate address space for\nkernel and user.\n\nThis function will be useful for other uses as well; for example, taking\ninput for /sysfs instead of /proc, so it was changed to accept kernel\nbuffers.  We have this use for the Linux UWB project, as part as the\nupcoming bandwidth allocator code.\n\nOnly a few routines used this function and they were changed too.\n\nSigned-off-by: Reinette Chatre \u003creinette.chatre@linux.intel.com\u003e\nSigned-off-by: Inaky Perez-Gonzalez \u003cinaky@linux.intel.com\u003e\nCc: Paul Jackson \u003cpj@sgi.com\u003e\nCc: Joe Korty \u003cjoe.korty@ccur.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
