13 mm: compaction: fix the migration stats in trace_mm_compaction_migratepages()
14
15 Now the migrate_pages() has changed to return the number of {normal
16 page, THP, hugetlb} instead, thus we should not use the return value to
17 calculate the number of pages migrated successfully. Instead we can
18 just use the 'nr_succeeded' which indicates the number of normal pages
19 migrated successfully to calculate the non-migrated pages in
20 trace_mm_compaction_migratepages().

13 btrfs: pass fs_info to trace_btrfs_transaction_commit
14
15 The root on the trans->root can be anything, and generally we're
16 committing from the transaction kthread so it's usually the tree_root.
17 Change this to just take an fs_info, and to maintain compatibility
18 simply put the ROOT_TREE_OBJECTID as the root objectid for the
19 tracepoint. This will allow use to remove trans->root.

12
13 random: rather than entropy_store abstraction, use global
14
15 Originally, the RNG used several pools, so having things abstracted out
16 over a generic entropy_store object made sense. These days, there's only
17 one input pool, and then an uneven mix of usage via the abstraction and
18 usage via &input_pool. Rather than this uneasy mixture, just get rid of
19 the abstraction entirely and have things always use the global. This
20 simplifies the code and makes reading it a bit easier.

12 net: skb: introduce kfree_skb_reason()
13
14 Introduce the interface kfree_skb_reason(), which is able to pass
15 the reason why the skb is dropped to 'kfree_skb' tracepoint.
16
17 Add the 'reason' field to 'trace_kfree_skb', therefor user can get
18 more detail information about abnormal skb with 'drop_monitor' or
19 eBPF.
20
21 All drop reasons are defined in the enum 'skb_drop_reason', and
22 they will be print as string in 'kfree_skb' tracepoint in format
23 of 'reason: XXX'.
24
25 ( Maybe the reasons should be defined in a uapi header file, so that
26 user space can use them? )
