2013-07-13llist: llist_add() can use llist_add_batch()Oleg Nesterov
llist_add(new, head) can simply use llist_add_batch(new, new, head), no need to duplicate the code. This obviously uninlines llist_add() and to me this is a win. But we can make llist_add_batch() inline if this is desirable, in this case gcc can notice that new_first == new_last if the caller is llist_add().

2013-07-13llist: fix/simplify llist_add() and llist_add_batch()Oleg Nesterov
1. This is mostly theoretical, but llist_add*() need ACCESS_ONCE(). Otherwise it is not guaranteed that the first cmpxchg() uses the same value for old_entry and new_last->next. 2. These helpers cache the result of cmpxchg() and read the initial value of head->first before the main loop. I do not think this makes sense. In the likely case cmpxchg() succeeds, otherwise it doesn't hurt to reload head->first. I think it would be better to simplify the code and simply read ->first before cmpxchg().

2013-07-13fput: turn "list_head delayed_fput_list" into llist_headOleg Nesterov
fput() and delayed_fput() can use llist and avoid the locking. This is unlikely path, it is not that this change can improve the performance, but this way the code looks simpler.

2013-07-13ext4: don't allow ext4_free_blocks() to fail due to ENOMEMTheodore Ts'o
The filesystem should not be marked inconsistent if ext4_free_blocks() is not able to allocate memory. Unfortunately some callers (most notably ext4_truncate) don't have a way to reflect an error back up to the VFS. And even if we did, most userspace applications won't deal with most system calls returning ENOMEM anyway.

2013-07-12ipv6: only static routes qualify for equal cost multipathingHannes Frederic Sowa
Static routes in this case are non-expiring routes which did not get configured by autoconf or by icmpv6 redirects. To make sure we actually get an ecmp route while searching for the first one in this fib6_node's leafs, also make sure it matches the ecmp route assumptions. v2: a) Removed RTF_EXPIRE check in dst.from chain. The check of RTF_ADDRCONF already ensures that this route, even if added again without RTF_EXPIRES (in case of a RA announcement with infinite timeout), does not cause the rt6i_nsiblings logic to go wrong if a later RA updates the expiration time later. v3: a) Allow RTF_EXPIRES routes to enter the ecmp route set. We have to do so, because an pmtu event could update the RTF_EXPIRES flag and we would not count this route, if another route joins this set. We now filter only for RTF_GATEWAY|RTF_ADDRCONF|RTF_DYNAMIC, which are flags that don't get changed after rt6_info construction.

You can turn on or off support for minorversions using e.g. echo "-4.2" >/proc/fs/nfsd/versions However, the current implementation is a little wonky. For example, the above will turn off 4.2 support, but it will also turn *on* 4.1 support. This didn't matter as long as we only had 2 minorversions, which was true till very recently. And do a little cleanup here. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2013-07-12perf report/top: Add option to collapse undesired parts of call graphGreg Price
For example, in an application with an expensive function implemented with deeply nested recursive calls, the default call-graph presentation is dominated by the different callchains within that function. By ignoring these callees, we can collect the callchains leading into the function and compactly identify what to blame for expensive calls. For example, in this report the callers of garbage_collect() are scattered across the tree: $ perf report -d ruby 2>- | grep -m10 ^[^#]*[a-z] 22.03% ruby [.] gc_mark --- gc_mark |--59.40%-- mark_keyvalue | st_foreach | gc_mark_children | |--99.75%-- rb_gc_mark | | rb_vm_mark | | gc_mark_children | | gc_marks | | |--99.00%-- garbage_collect If we ignore the callees of garbage_collect(), its callers are coalesced: $ perf report --ignore-callees garbage_collect -d ruby 2>- | grep -m10 ^[^#]*[a-z] 72.92% ruby [.] garbage_collect --- garbage_collect vm_xmalloc |--47.08%-- ruby_xmalloc | st_insert2 | rb_hash_aset | |--98.45%-- features_index_add | | rb_provide_feature | | rb_require_safe | | vm_call_method Signed-off-by: Greg Price <price@mit.edu> Tested-by: Jiri Olsa <jolsa@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/20130623031720.GW22203@biohazard-cafe.mit.edu Link: http://lkml.kernel.org/r/20130708115746.GO22203@biohazard-cafe.mit.edu Cc: Fengguang Wu <fengguang.wu@intel.com> [ remove spaces at beginning of line, reported by Fengguang Wu ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
