[PATCH/GIT PULL] Cleanups and bug-fix in tmem for v4.5 (v2.1)

[Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>]

Hey Jan,

Please git pull the following branch:

 git pull git://xenbits.xen.org/people/konradwilk/xen.git stable/tmem-for-4.5.v2.1


These patches, except one, had been posted at the beginning of the year
by Bob - mostly (more on this later). The last patch:

 [PATCH v2.1 15/15] xen: tmem: tmem_try_to_evict_pgp: fix a lock issue

is new and is a bug-fix for an issue that had been in tmem for quite
some time.

The rest of the patchset is:
 - An extra bugfix for a potential race,
 - Cleanups.

They have been tested extensively over 72 hours with almost no memory
available to make sure that the error paths are also exercised.

The patch:
 [PATCH v2.1 05/15] tmem: cleanup: remove unneed parameter from pgp_delist()  

is slightly different than the posted version - as a bug-fix had been
rolled in it (an two line change).

For your convience - I am also emailing the patches in case you would
prefer to look at those instead of doing a 'git pull'


Thanks!
