Subject: [PATCH v2 0/8] hoist uuid helpers from xfs to linux/uuid.h
Date: Thu,  4 May 2017 16:26:15 +0300	[thread overview]

Darick,

I moved some code around to be able to hoist all the generic
xfs uuid helpers to linux/uuid.h, so that other filesystems
and uuid related code in the kernel can use them.

Let me know what you think of the outcome.

I did not find any uuid related regressions with xfs.
Specifically, the following xfstests exercise these changes:
xfs/045 xfs/073 xfs/077 (multi uuid mount)
generic/079 xfs/238 xfs/269 xfs/062 (fshandle)

Some of these helpers are quite similar to thier uuid_{le|be}
variants in linux/uuid.h, but at the moment I don't see xfs
or any filesystem starting to use the uuid_{le|be} helpers,
so we probably have to live with this duplicity for a while
longer.

Amir.

Amir Goldstein (8):
  xfs: use uuid_copy() helper to abstract uuid_t
  xfs: re-define uuid_t as common struct uuid_v1
  xfs: dismiss xfs_uu_t
  xfs: namespace the helper uuid_getnodeuniq()
  md: namespace private helper names
  linux/uuid.h: hoist helpers uuid_equal() and uuid_copy() from xfs
  linux/uuid.h: hoist uuid_is_null() helper from libnvdimm
  xfs: use the common helper uuid_is_null()
