commit 359d992bcd398273637cd9edde10afca953783c4
Author: Gu Zheng <guz.fnst@cn.fujitsu.com>

    xfs: simplify kmem_{zone_}zalloc
    
    Introduce flag KM_ZERO which is used to alloc zeroed entry, and convert
    kmem_{zone_}zalloc to call kmem_{zone_}alloc() with KM_ZERO directly,
    in order to avoid the setting to zero step.
    And following Dave's suggestion, make kmem_{zone_}zalloc static inline
    into kmem.h as they're now just a simple wrapper.
    
    V2:
      Make kmem_{zone_}zalloc static inline into kmem.h as Dave suggested.

    xfs: add tracepoints to AGF/AGI read operations
    
    To help track down AGI/AGF lock ordering issues, I added these
    tracepoints to tell us when an AGI or AGF is read and locked.  With
    these we can now determine if the lock ordering goes wrong from
    tracing captures.

    xfs: trace AIL manipulations
    
    I debugging a log tail issue on a RHEL6 kernel, I added these trace
    points to trace log items being added, moved and removed in the AIL
    and how that affected the log tail LSN that was written to the log.
    They were very helpful in that they immediately identified the cause
    of the problem being seen. Hence I'd like to always have them
    available for use.
