The cgroup_mutex, which was removed by the\ncommit, in mem_cgroup_out_of_memory() was originally introduced at commit\nc7ba5c9e (Memory controller: OOM handling).\n\nIIUC, the intention of this cgroup_mutex was to prevent task move during\nselect_bad_process() so that situations like below can be avoided.\n\n  Assume cgroup \"foo\" has exceeded its limit and is about to trigger oom.\n  1. Process A, which has been in cgroup \"baa\" and uses large memory, is just\n     moved to cgroup \"foo\". Process A can be the candidates for being killed.\n  2. Process B, which has been in cgroup \"foo\" and uses large memory, is just\n     moved from cgroup \"foo\". Process B can be excluded from the candidates for\n     being killed.\n\nBut these race window exists anyway even if we hold a lock, because\n__mem_cgroup_try_charge() decides wether it should trigger oom or not\noutside of the lock.  So the original cgroup_mutex in\nmem_cgroup_out_of_memory and thus current memcg_tasklist has no use.  And\nIMHO, those races are not so critical for users.\n\nThis patch removes it and make codes simpler.\n\nSigned-off-by: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nCc: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "intelfb: fix setting of active pipe with LVDS displays\n\nThe intelfb driver sets color map depending on currently active pipe.\nHowever, if an LVDS display is attached (like in laptop) the active pipe\nvariable is never set.  The default value is PIPE_A and can be wrong.  Set\nup the pipe variable during driver initialization after hardware state was\nread.\n\nAlso, the detection of the active display (and hence the pipe) is wrong.\nThe pipes are assigned to so called planes.  Both pipes are always enabled\non my laptop but only one plane is enabled (the plane A for the CRT or the\nplane B for the LVDS).  Change active pipe detection code to take into\naccount a status of the plane assigned to each pipe.\n\nThe problem is visible in the 8 bpp mode if colors above 15 are used.  The\nfirst 16 color entries are displayed correctly.\n\nThe graphics chip description is here (G45 vol. 3):\nhttp://intellinuxgraphics.org/documentation.html\n\nAddresses http://bugzilla.kernel.org/show_bug.cgi?id\u003d13285\n\nSigned-off-by: Krzysztof Helt \u003ckrzysztof.h1@wp.pl\u003e\nCc: Michal Suchanek \u003chramrach@centrum.cz\u003e\nCc: Dean Menezes \u003csamanddeanus@yahoo.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "autofs4: eliminate d_unhashed in path walk checks\n\nWe unhash the dentry (in a subsequent patch) in -\u003ed_revalidate() in order\nto send mount requests to -\u003elookup().  But then we can not rely on\nd_unhased() to give reliable results because it may be called at any time\nby any code path.  The d_unhashed() function is used by __simple_empty()\nin the path walking callbacks but autofs mount point dentrys should have\nno directories at all so a list_empty() on d_subdirs should be (and is)\nsufficient.\n\nSigned-off-by: Ian Kent \u003craven@themaw.net\u003e\nCc: Sage Weil \u003csage@newdream.net\u003e\nCc: Al Viro \u003cviro@ZenIV.linux.org.uk\u003e\nCc: Andreas Dilger \u003cadilger@sun.com\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Yehuda Saheh \u003cyehuda@newdream.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
