This patch avoids the following sparse warning: fs/dlm/user.c:111:38: warning: incorrect type in assignment (different address spaces) fs/dlm/user.c:111:38: expected void [noderef] __user *castparam fs/dlm/user.c:111:38: got void * fs/dlm/user.c:112:37: warning: incorrect type in assignment (different address spaces) fs/dlm/user.c:112:37: expected void [noderef] __user *castaddr fs/dlm/user.c:112:37: got void * fs/dlm/user.c:113:38: warning: incorrect type in assignment (different address spaces) fs/dlm/user.c:113:38: expected void [noderef] __user *bastparam fs/dlm/user.c:113:38: got void * fs/dlm/user.c:114:37: warning: incorrect type in assignment (different address spaces) fs/dlm/user.c:114:37: expected void [noderef] __user *bastaddr fs/dlm/user.c:114:37: got void * fs/dlm/user.c:115:33: warning: incorrect type in assignment (different address spaces) fs/dlm/user.c:115:33: expected struct dlm_lksb [noderef] __user *lksb fs/dlm/user.c:115:33: got void * fs/dlm/user.c:130:39: warning: cast removes address space '__user' of expression fs/dlm/user.c:131:40: warning: cast removes address space '__user' of expression fs/dlm/user.c:132:36: warning: cast removes address space '__user' of expression So far I see there is no direct handling of copying a pointer value to another pointer value. The handling only copies the actual pointer address to a scalar type or vice versa. This should be okay because it never handles dereferencing anything of those addresses in the kernel space. To get rid of those warnings we doing some different casting which results in no warnings in sparse or compiler.
