      Btrfs: fix delalloc reservation amount tracepoint · f485c9ee
      Josef Bacik 提交于
      We can sometimes drop the reservation we had for our inode, so we need to remove
      that amount from to_reserve so that our tracepoint reports a valid amount of
      space.

      Btrfs: introduce ticketed enospc infrastructure · 957780eb
      Josef Bacik 提交于
      Our enospc flushing sucks.  It is born from a time where we were early
      enospc'ing constantly because multiple threads would race in for the same
      reservation and randomly starve other ones out.  So I came up with this solution
      to block any other reservations from happening while one guy tried to flush
      stuff to satisfy his reservation.  This gives us pretty good correctness, but
      completely crap latency.
      
      The solution I've come up with is ticketed reservations.  Basically we try to
      make our reservation, and if we can't we put a ticket on a list in order and
      kick off an async flusher thread.  This async flusher thread does the same old
      flushing we always did, just asynchronously.  As space is freed and added back
      to the space_info it checks and sees if we have any tickets that need
      satisfying, and adds space to the tickets and wakes up anything we've satisfied.
      
      Once the flusher thread stops making progress it wakes up all the current
      tickets and tells them to take a hike.
      
      There is a priority list for things that can't flush, since the async flusher
      could do anything we need to avoid deadlocks.  These guys get priority for
      having their reservation made, and will still do manual flushing themselves in
      case the async flusher isn't running.
      
      This patch gives us significantly better latencies.  Thanks,

      Btrfs: change delayed reservation fallback behavior · c48f49d6
      Josef Bacik 提交于
      We reserve space for the inode update when we first reserve space for writing to
      a file.  However there are lots of ways that we can use this reservation and not
      have it for subsequent ordered extents.  Previously we'd fall through and try to
      reserve metadata bytes for this, then we'd just steal the full reservation from
      the delalloc_block_rsv, and if that didn't have enough space we'd steal the full
      reservation from the global reserve.  The problem with this is we can easily
      just return ENOSPC and fallback to updating the inode item directly.  In the
      worst case (assuming 4k nodesize) we'd steal 64kib from the global reserve if we
      fall all the way through, however if we just fallback and update the inode
      directly we'd only steal 4k * BTRFS_PATH_MAX in the worst case which is 32kib.
      
      We would have also just added the extent item for the inode so we likely will
      have already cow'ed down most of the way to the leaf containing the inode item,
      so we are more often than not only need one or two nodesize's worth of
      reservations.  Given the reservation for the extent itself is also a worst case
      we will likely already have space to cover the inode update.
      
      This change will make us behave better in the theoretical worst case, and much
      better in the case that we don't have our reservation and cannot reserve more
      metadata.  Thanks,

      Btrfs: always reserve metadata for delalloc extents · 48c3d480
      Josef Bacik 提交于
      There are a few races in the metadata reservation stuff.  First we add the bytes
      to the block_rsv well after we've set the bit on the inode saying that we have
      space for it and after we've reserved the bytes.  So use the normal
      btrfs_block_rsv_add helper for this case.  Secondly we can flush delalloc
      extents when we try to reserve space for our write, which means that we could
      have used up the space for the inode and we wouldn't know because we only check
      before the reservation.  So instead make sure we are always reserving space for
      the inode update, and then if we don't need it release those bytes afterward.

      Btrfs: fix callers of btrfs_block_rsv_migrate · 25d609f8
      Josef Bacik 提交于
      So btrfs_block_rsv_migrate just unconditionally calls block_rsv_migrate_bytes.
      Not only this but it unconditionally changes the size of the block_rsv.  This
      isn't a bug strictly speaking, but it makes truncate block rsv's look funny
      because every time we migrate bytes over its size grows, even though we only
      want it to be a specific size.  So collapse this into one function that takes an
      update_size argument and make truncate and evict not update the size for
      consistency sake.  Thanks,

      Btrfs: add bytes_readonly to the spaceinfo at once · e40edf2d
      Josef Bacik 提交于
      For some reason we're adding bytes_readonly to the space info after we update
      the space info with the block group info.  This creates a tiny race where we
      could over-reserve space because we haven't yet taken out the bytes_readonly
      bit.  Since we already know this information at the time we call
      update_space_info, just pass it along so it can be updated all at once.  Thanks,

      ovl: warn instead of error if d_type is not supported · e7c0b599
      Vivek Goyal 提交于
      overlay needs underlying fs to support d_type. Recently I put in a
      patch in to detect this condition and started failing mount if
      underlying fs did not support d_type.
      
      But this breaks existing configurations over kernel upgrade. Those who
      are running docker (partially broken configuration) with xfs not
      supporting d_type, are surprised that after kernel upgrade docker does
      not run anymore.
      
      https://github.com/docker/docker/issues/22937#issuecomment-229881315
      
      So instead of erroring out, detect broken configuration and warn
      about it. This should allow existing docker setups to continue
      working after kernel upgrade.

      There are multiple ingredients for this:
      
       1) PAGE_NONE is defined to _CACHE_CACHABLE_NONCOHERENT, which is CCA 3
          on all platforms except SB1 where it's CCA 5.
       2) _page_cachable_default must have bits set which are not set
          _CACHE_CACHABLE_NONCOHERENT.
       3) Either the defective version of pte_modify for XPA or the standard
          version must be in used.  However pte_modify for the 36 bit address
          space support is no affected.
      
      In that case additional bits in the final CCA mode may generate an invalid
      value for the CCA field.  On the R10000 system where this was tracked
      down for example a CCA 7 has been observed, which is Uncached Accelerated.
      
      Fixed by:
      
       1) Using the proper CCA mode for PAGE_NONE just like for all the other
          PAGE_* pte/pmd bits.
       2) Fix the two affected variants of pte_modify.
      
      Further code inspection also shows the same issue to exist in pmd_modify
      which would affect huge page systems.
      
      Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE
      and pmd_modify issue found by me.
      
      The history of this goes back beyond Linus' git history.  Chris Dearman's
      commit 35133692 ("[MIPS] Allow setting of
      the cache attribute at run time.") missed the opportunity to fix this
      but it was originally introduced in lmo commit
      d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.")
      and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option

       "Three cpufreq fixes, one in the core (stable-candidate) and two in

         - Fix a recent intel_pstate regression that caused the number of
           wakeups to increase significantly on an idle system in some cases
           due to excessive synchronize_sched() invocations (Rafael Wysocki).

           cpufreq has been suspended introduced during the 4.6 cycla (Rafael
           Wysocki).

      Pull libnvdimm fixes from Dan Williams:
       "1/ Two regression fixes since v4.6: one for the byte order of a sysfs
           attribute (bz121161) and another for QEMU 2.6's NVDIMM _DSM (ACPI
           Device Specific Method) implementation that gets tripped up by new
           auto-probing behavior in the NFIT driver.
      
        2/ A fix tagged for -stable that stops the kernel from
           clobbering/ignoring changes to the configuration of a 'pfn'
           instance ("struct page" driver).  For example changing the
           alignment from 2M to 1G may silently revert to 2M if that value is
           currently stored on media.
      
        3/ A fix from Eric for an xfstests failure in dax.  It is not
           currently tagged for -stable since it requires an 8-exabyte file
           system to trigger, and there appear to be no user visible side
           effects"
