[PATCH 0/4] taskstats: four more tidy-ups in the genl path

[Bradley Morgan]

Four small cleanups from reading kernel/taskstats.c again.  No functional
change in any of them.

Patch 1 uses nla_put_u32() in mk_reply() instead of open coding the u32
attribute with nla_put() and a sizeof/& pair.

Patch 2 grabs the inode once with file_inode() in exe_add_tsk(), which
walks exe_file->f_inode twice today, once for the device and once for the
number.

Patch 3 reads the cgroupstats fd out of na, which the function already
fetched, instead of indexing info->attrs[] again for the same attribute.

Patch 4 converts the elapsed time with div_u64() in
tgid_stats_add_task(), like the utime and stime lines four below it do,
instead of do_div().

old gmail address.

Bradley Morgan (4):
  taskstats: use nla_put_u32() in mk_reply()
  taskstats: take the inode once in exe_add_tsk()
  taskstats: reuse na in cgroupstats_user_cmd()
  taskstats: use div_u64() for the elapsed time in tgid_stats_add_task()
