      spi/dw_spi: Fix missing header · 46165a3d
      Jiri Slaby 提交于
      Currently, build on PPC dies with:
      In file included from drivers/spi/dw_spi_mmio.c:16:
      include/linux/spi/dw_spi.h:147: error: field ‘tx_sgl’ has incomplete type
      include/linux/spi/dw_spi.h:149: error: field ‘rx_sgl’ has incomplete type
      
      Add linux/scatterlist.h include to dw_spi.h, because we need to know
      the contents of the structure.

      fs: call security_d_instantiate in d_obtain_alias V2 · 24ff6663
      Josef Bacik 提交于
      While trying to track down some NFS problems with BTRFS, I kept noticing I was
      getting -EACCESS for no apparent reason.  Eric Paris and printk() helped me
      figure out that it was SELinux that was giving me grief, with the following
      denial
      
      type=AVC msg=audit(1290013638.413:95): avc:  denied  { 0x800000 } for  pid=1772
      comm="nfsd" name="" dev=sda1 ino=256 scontext=system_u:system_r:kernel_t:s0
      tcontext=system_u:object_r:unlabeled_t:s0 tclass=file
      
      Turns out this is because in d_obtain_alias if we can't find an alias we create
      one and do all the normal instantiation stuff, but we don't do the
      security_d_instantiate.
      
      Usually we are protected from getting a hashed dentry that hasn't yet run
      security_d_instantiate() by the parent's i_mutex, but obviously this isn't an
      option there, so in order to deal with the case that a second thread comes in
      and finds our new dentry before we get to run security_d_instantiate(), we go
      ahead and call it if we find a dentry already.  Eric assures me that this is ok
      as the code checks to see if the dentry has been initialized already so calling
      security_d_instantiate() against the same dentry multiple times is ok.  With
      this patch I'm no longer getting errant -EACCESS values.
