      fix __swap_writepage() compile failure on old gcc versions · 05064084

      Tetsuo Handa wrote:
       "Commit 62a8067a ("bio_vec-backed iov_iter") introduced an unnamed
        union inside a struct which gcc-4.4.7 cannot handle.  Name the unnamed
         union as u in order to fix build failure"
      
      Let's do this instead: there is only one place in the entire tree that
      steps into this breakage.  Anon structs and unions work in older gcc
      versions; as the matter of fact, we have those in the tree - see e.g.
      struct ieee80211_tx_info in include/net/mac80211.h
      
      What doesn't work is handling their initializers:
      
      struct {
      	int a;
      	union {
      		int b;
      		char c;
      	};
      } x[2] = {{.a = 1, .c = 'a'}, {.a = 0, .b = 1}};
      
      is the obvious syntax for initializer, perfectly fine for C11 and
      handled correctly by gcc-4.7 or later.
      
      Earlier versions, though, break on it - declaration is fine and so's
      access to fields (i.e.  x[0].c = 'a'; would produce the right code), but
      members of the anon structs and unions are not inserted into the right
      namespace.  Tellingly, those older versions will not barf on struct {int
      a; struct {int a;};}; - looks like they just have it hacked up somewhere
      around the handling of .  and -> instead of doing the right thing.
      
      The easiest way to deal with that crap is to turn initialization of
      those fields (in the only place where we have such initializer of
      iov_iter) into plain assignment.

      x86/vdso: Fix vdso_install · a934fb5b
      Andy Lutomirski authored
      "make vdso_install" installs unstripped versions of the vdso objects
      for the benefit of the debugger.  This was broken by checkin:
      
      6f121e54 x86, vdso: Reimplement vdso.so preparation in build-time C
      
      The filenames are different now, so update the Makefile to cope.
      
      This still installs the 64-bit vdso as vdso64.so.  We believe this
      will be okay, as the only known user is a patched gdb which is known
      to use build-ids, but if it turns out to be a problem we may have to
      add a link.
      
      Inspired by a patch from Sam Ravnborg.

      NVMe: Fix START_STOP_UNIT Scsi->NVMe translation. · b8e08084
      Dan McLeran authored
      This patch contains several fixes for Scsi START_STOP_UNIT. The previous
      code did not account for signed vs. unsigned arithmetic which resulted
      in an invalid lowest power state caculation when the device only supports
      1 power state.
      
      The code for Power Condition == 2 (Idle) was not following the spec. The
      spec calls for setting the device to specific power states, depending
      upon Power Condition Modifier, without accounting for the number of
      power states supported by the device.
      
      The code for Power Condition == 3 (Standby) was using a hard-coded '0'
      which is replaced with the macro POWER_STATE_0.

      btrfs: fix use of uninit "ret" in end_extent_writepage() · 3e2426bd
      Eric Sandeen authored
      If this condition in end_extent_writepage() is false:
      
      	if (tree->ops && tree->ops->writepage_end_io_hook)
      
      we will then test an uninitialized "ret" at:
      
      	ret = ret < 0 ? ret : -EIO;
      
      The test for ret is for the case where ->writepage_end_io_hook
      failed, and we'd choose that ret as the error; but if
      there is no ->writepage_end_io_hook, nothing sets ret.
      
      Initializing ret to 0 should be sufficient; if
      writepage_end_io_hook wasn't set, (!uptodate) means
      non-zero err was passed in, so we choose -EIO in that case.

      Btrfs: fix qgroups sanity test crash or hang · b050f9f6
      Filipe Manana authored
      Often when running the qgroups sanity test, a crash or a hang happened.
      This is because the extent buffer the test uses for the root node doesn't
      have an header level explicitly set, making it have a random level value.
      This is a problem when it's not zero for the btrfs_search_slot() calls
      the test ends up doing, resulting in crashes or hangs such as the following:

      Btrfs: fix unfinished readahead thread for raid5/6 degraded mounting · 5fbc7c59
      Wang Shilong authored
      Steps to reproduce:
      
       # mkfs.btrfs -f /dev/sd[b-f] -m raid5 -d raid5
       # mkfs.ext4 /dev/sdc --->corrupt one of btrfs device
       # mount /dev/sdb /mnt -o degraded
       # btrfs scrub start -BRd /mnt
      
      This is because readahead would skip missing device, this is not true
      for RAID5/6, because REQ_GET_READ_MIRRORS return 1 for RAID5/6 block
      mapping. If expected data locates in missing device, readahead thread
      would not call __readahead_hook() which makes event @rc->elems=0
      wait forever.
      
      Fix this problem by checking return value of btrfs_map_block(),we
      can only skip missing device safely if there are several mirrors.

      btrfs: new ioctl TREE_SEARCH_V2 · cc68a8a5
      Gerhard Heift authored
      This new ioctl call allows the user to supply a buffer of varying size in which
      a tree search can store its results. This is much more flexible if you want to
      receive items which are larger than the current fixed buffer of 3992 bytes or
      if you want to fetch more items at once. Items larger than this buffer are for
      example some of the type EXTENT_CSUM.

      NVMe: Fix hot cpu notification dead lock · f3db22fe
      Keith Busch authored
      There is a potential dead lock if a cpu event occurs during nvme probe
      since it registered with hot cpu notification. This fixes the race by
      having the module register with notification outside of probe rather
      than have each device register.
      
      The actual work is done in a scheduled work queue instead of in the
      notifier since assigning IO queues has the potential to block if the
      driver creates additional queues.

       "Here are the remaining bits I was mentioning earlier.  Mostly bug
        fixes and new selftests from Michael (yay !).  He also removed the WSP
        platform and A2 core support which were dead before release, so less
        clutter.
      
        One little "feature" I snuck in is the doorbell IPI support for
        non-virtualized P8 which speeds up IPIs significantly between threads
        of a core"

      x86/vdso: Hack to keep 64-bit Go programs working · e0bf7b86
      Andy Lutomirski authored
      The Go runtime has a buggy vDSO parser that currently segfaults.
      This writes an empty SHT_DYNSYM entry that causes Go's runtime to
      malfunction by thinking that the vDSO is empty rather than
      malfunctioning by running off the end and segfaulting.
      
      This affects x86-64 only as far as we know, so we do not need this for
      the i386 and x32 vdsos.
