drivers/misc/sgi-gru/grukdump.c: cleanup gru_dump_context() a little

2014-04-07T23:36:09+00:00

"ret" is zero here so we can remove the "!ret" part of the condition. "uhdr" is alread a __user pointer so we can remove the cast. Signed-off-by: Dan Carpenter Acked-by: Dimitri Sivanich Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/misc/sgi-gru/grukdump.c: unlocking should be conditional in gru_dump_context()

2014-02-11T00:01:39+00:00

I was reviewing this and noticed that unlocking should be conditional on the error path. I've changed it to unlock and return directly since we only do it once and it seems unlikely to change in the near future.

drivers/misc/sgi-gru/grufault.c: fix a sanity test in gru_set_context_option()

2013-07-03T23:07:42+00:00

"req.val1 == -1" is valid but it doesn't make sense to check gru_base[-1]. gru_base[] is a global array. Signed-off-by: Dimitri Sivanich Cc: Dan Carpenter Cc: Robin Holt Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

We want the fixes in here.

drivers/misc/sgi-gru/grufile.c: fix info leak in gru_get_config_info()

The "info.fill" array isn't initialized so it can leak uninitialized stack information to user space. Signed-off-by: Dan Carpenter Acked-by: Robin Holt Acked-by: Dimitri Sivanich Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

misc: replace strict_strtoul() with kstrtoul()

2013-06-06T19:54:08+00:00

The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han Reviewed-by: Andy Shevchenko Signed-off-by: Greg Kroah-Hartman

proc: Supply a function to remove a proc entry by PDE

2013-05-01T21:29:46+00:00

Supply a function (proc_remove()) to remove a proc entry (and any subtree rooted there) by proc_dir_entry pointer rather than by name and (optionally) root dir entry pointer. This allows us to eliminate all remaining pde->name accesses outside of procfs.

hlist: drop the node parameter from iterators

2013-02-28T03:10:24+00:00

I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin Acked-by: Paul E.
