Sync current instrumentation for linux 3.8
The patch bundles following changes:
* Sync ext4, rcu, btrfs mainline header
* b564553 ext4: print 'flags' in ext4_ext_handle_uninitialized_extents
* 19b303d ext4: print map->m_flags in trace_ext4_ext/ind_map_blocks_exit
* 992e9fd ext4: add some tracepoints in extent status tree
* fb57dc8 Btrfs: parse parent 0 into correct value in tracepoint
This fix also apply to previous kernel version, thus no conditional is
required.
* 4520fb3 ext4: split off ext4_journalled_invalidatepage()
* Add required includes for ext4 tracepoints. The function
ext4_ext_get_actual_len() called from ext4 tracepoints requires additional
includes.
I just encountered that indeed. Here is a pastebin with the compile errors.
The current instrumentation is now synced to 3.9, thus this issue can be closed.
