How about:
#define push_root() \recursive_mutex_lock(&context->id_lock); \context->uid = current->fsuid; \context->gid = current->fsgid; \do { \
struct cred *new1 = prepare_creds(); \
//make changes to any member of this structure \
commit_creds(new1); \} while(0);

Here is the macroNow this driver is at 2.6.18 kernel. I have to upgrade it to 3.8.3.As I have said"current" in kernel is a global macro, that always point to the "struct task_struct * " of the currently executing task (for details on task_struct, ref Robert Love, pg 24-27).
Now if you look at thse two lines-current->fsuid = 0; \current->fsgid = 0
Now task struct does not contain fsuid and fsgid, instead you havestruct cred containing fsuid and fsgid.So normal method isstruct cred *new1;
new1 =prepare_creds();
//make changes to any member of this structure
commit_creds(new1);
Now this above action I need to perform through a macro, in order to bring minimal changes to the driver.Now, I have told everything. Can someone suggest something that might work.
