* sched/headers: Prepare to remove the <linux/mm_types.h> dependency from ↵Ingo Molnar2017-03-022-2/+2
| | | | | | | | | | | | | | | <linux/sched.h> Update code that relied on sched.h including various MM types for them. This will allow us to remove the <linux/mm_types.h> include from <linux/sched.h>.

* sched/headers: Prepare for the reduction of <linux/sched.h>'s signal API ↵Ingo Molnar2017-03-028-0/+10
| | | | | | | | | | | | | | | | | | | | dependency Instead of including the full <linux/signal.h>, we are going to include the types-only <linux/signal_types.h> header in <linux/sched.h>, to further decouple the scheduler header from the signal headers. This means that various files which relied on the full <linux/signal.h> need to be updated to gain an explicit dependency on it. Update the code that relies on sched.h's inclusion of the <linux/signal.h> header.

* sched/headers, cgroups: Remove the threadgroup_change_*() wrapperyIngo Molnar2017-03-021-3/+3
| | | | | | | | | | | | | | | | | | | | | | threadgroup_change_begin()/end() is a pointless wrapper around cgroup_threadgroup_change_begin()/end(), minus a might_sleep() in the !CONFIG_CGROUPS=y case. Remove the wrappery, move the might_sleep() (the down_read() already has a might_sleep() check). This debloats <linux/sched.h> a bit and simplifies this API. Update all call sites. No change in functionality.

* rcu: Separate the RCU synchronization types and APIs into ↵Ingo Molnar2017-03-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <linux/rcupdate_wait.h> So rcupdate.h is a pretty complex header, in particular it includes <linux/completion.h> which includes <linux/wait.h> - creating a dependency that includes <linux/wait.h> in <linux/sched.h>, which prevents the isolation of <linux/sched.h> from the derived <linux/wait.h> header. Solve part of the problem by decoupling rcupdate.h from completions: this can be done by separating out the rcu_synchronize types and APIs, and updating their usage sites. Since this is a mostly RCU-internal types this will not just simplify <linux/sched.h>'s dependencies, but will make all the hundreds of .c files that include rcupdate.h but not completions or wait.h build faster. ( For rcutiny this means that two dependent APIs have to be uninlined, but that shouldn't be much of a problem as they are rare variants. ) Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul E.

| | | | | | | | | | | | | | | | | | | | An interrupted rename will leave the old dentry behind if the rename succeeds. Fix this by moving the final local work of the rename to rpc_call_done so that the results of the RENAME can always be handled, even if the original process has already returned with -ERESTARTSYS.

| * NFS: Remove unnecessary goto in nfs4_lookup_root_sec()Anna Schumaker2017-01-301-8/+3
| | | | | | | | | | | | Once again, it's easier and cleaner just to return the error directly. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
| * NFS: Remove nfs4_recover_expired_lease()Anna Schumaker2017-01-301-6/+1
| | | | | | | | | | | | | | This function doesn't add much, since all it does is access the server's nfs_client variable. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>

| | | | | | | | | | | | | | There is no need for a goto just to return an error code without any cleanup. Returning the error directly helps to clean up the code. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>

| | | | | | | | | | | | | | | | | | This tracepoint displays information about the slot that was chosen for the RPC, in addition to session information. This could be useful information for debugging, and we can set the session id hash to 0 to indicate that there is no session. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
