    Description

      Some entries can end up being duplicated in "actions". For instance:

      lrh=[type=10680000 len=136 idx=1/14] fid=[0x200000401:0x10:0x0] dfid=[0x200000401:0x10:0x0] compound/cookie=0x5703ea60/0x5703ea6c action=ARCHIVE archive#=1 flags=0x0 extent=0x0-0xffffffffffffffff gid=0x0 datalen=0 status=WAITING data=[]
lrh=[type=10680000 len=136 idx=1/51633] fid=[0x200000401:0x10:0x0] dfid=[0x200000401:0x10:0x0] compound/cookie=0x5703ea60/0x5703ea6c action=ARCHIVE archive#=1 flags=0x0 extent=0x0-0xffffffffffffffff gid=0x0 datalen=0 status=STARTED data=[]
a

      As cdt_llog_lock is taken in mdt_hsm_actions_proc_show(), I think that could be a race between the coordinator/client and the proc_show() function.
