      nfs: plug memory leak when ->prepare_layoutcommit fails · 3471648a
      Jeff Layton authored
      "data" is currently leaked when the prepare_layoutcommit operation
      returns an error. Put the cred before taking the spinlock in that
      case, take the lock and then goto out_unlock which will drop the
      lock and then free "data".

      Thomas Gleixner authored
      Toshi explains:
      
      "No, the default values need to be set to the fallback types,
       i.e. minimal supported mode.  For WC and WT, UC is the fallback type.
      
       When PAT is disabled, pat_init() does update the tables below to
       enable WT per the default BIOS setup.  However, when PAT is enabled,
       but CPU has PAT -errata, WT falls back to UC per the default values."

      The CQM task events are not safe to be called from within interrupt
      context because they require performing an IPI to read the counter value
      on all sockets. And performing IPIs from within IRQ context is a
      "no-no".
      
      Make do with the last read counter value currently event in
      event->count when we're invoked in this context.

      libnvdimm: fix namespace seed creation · 8ca24353
      Dan Williams authored
      A new BLK namespace "seed" device is created whenever the current seed
      is successfully probed.  However, if that namespace is assigned to a BTT
      it may never directly experience a successful probe as it is a
      subordinate device to a BTT configuration.
      
      The effect of the current code is that no new namespaces can be
      instantiated, after the seed namespace, to consume available BLK DPA
      capacity.  Fix this by treating a successful BTT probe event as a
      successful probe event for the backing namespace.

      f2fs: call set_page_dirty to attach i_wb for cgroup · 6282adbf
      Jaegeuk Kim authored
      The cgroup attaches inode->i_wb via mark_inode_dirty and when set_page_writeback
      is called, __inc_wb_stat() updates i_wb's stat.
      
      So, we need to explicitly call set_page_dirty->__mark_inode_dirty in prior to
      any writebacking pages.
      
      This patch should resolve the following kernel panic reported by Andreas Reis.

       "Four smaller fixes for the current series.  This contains:
      
         - A fix for clones of discard bio's, that can cause data corruption.
           From Martin.
      
         - A fix for null_blk, where in certain queue modes it could access a
           request after it had been freed.  From Mike Krinkin.
      
         - An error handling leak fix for blkcg, from Tejun.
      
         - Also from Tejun, export of the functions that a file system needs
           to implement cgroup writeback support"

       "A couple important fixes.
      
         - A block layer change which removed restriction on max transfer size
           led to silent data corruption on some devices.  A new quirk is
           added to restore the old size limit for the reported device.  If it
           gets reported on more devices, we might have to consider restoring
           the restriction for ATA devices by default.
      
         - There finally is a SSD which is confirmed to cause data corruption
           on TRIM regardless of which flavor is used.  A new quirk is added
           and the device is blacklisted
      
         - Other device-specific workarounds"
