      ALSA: Fix dependency of CONFIG_SND_TEA575X · df944f66
      Takashi Iwai authored
      
      
      CONFIG_SND_TEA575X is enabled by RADIO_SF16FMR2, but the latter one is
      no PCI device.  Since tea575x-tuner itself is independent from the board
      bus type, the config should be moved out of SND_PCI dependency.

      ALSA: asihpi - use kzalloc() · 67ada836
      Thomas Meyer authored
       Use kzalloc rather than kmalloc followed by memset with 0
      
       This considers some simple cases that are common and easy to validate
       Note in particular that there are no ...s in the rule, so all of the
       matched code has to be contiguous
      
       The semantic patch that makes this output is available
       in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.

      Fix POSIX ACL permission check · 206b1d09
      Ari Savolainen authored
      After commit 3567866b
      
      : "RCUify freeing acls, let check_acl() go ahead in
      RCU mode if acl is cached" posix_acl_permission is being called with an
      unsupported flag and the permission check fails. This patch fixes the issue.

      vfs: optimize inode cache access patterns · 3ddcd056
      Linus Torvalds authored
      
      
      The inode structure layout is largely random, and some of the vfs paths
      really do care.  The path lookup in particular is already quite D$
      intensive, and profiles show that accessing the 'inode->i_op->xyz'
      fields is quite costly.
      
      We already optimized the dcache to not unnecessarily load the d_op
      structure for members that are often NULL using the DCACHE_OP_xyz bits
      in dentry->d_flags, and this does something very similar for the inode
      ops that are used during pathname lookup.
      
      It also re-orders the fields so that the fields accessed by 'stat' are
      together at the beginning of the inode structure, and roughly in the
      order accessed.
      
      The effect of this seems to be in the 1-2% range for an empty kernel
      "make -j" run (which is fairly kernel-intensive, mostly in filename
      lookup), so it's visible.  The numbers are fairly noisy, though, and
      likely depend a lot on exact microarchitecture.  So there's more tuning
      to be done.

      vfs: renumber DCACHE_xyz flags, remove some stale ones · 830c0f0e
      Linus Torvalds authored
      
      
      Gcc tends to generate better code with small integers, including the
      DCACHE_xyz flag tests - so move the common ones to be first in the list.
      Also just remove the unused DCACHE_INOTIFY_PARENT_WATCHED and
      DCACHE_AUTOFS_PENDING values, their users no longer exists in the source
      tree.
      
      And add a "unlikely()" to the DCACHE_OP_COMPARE test, since we want the
      common case to be a nice straight-line fall-through.
