      Unfortunately perf can't deal with anything other than direct structure
      accesses in the TP_printk() section.  It will drop dead when it sees
      jbd2_dev_to_name() in the "print fmt" section of the tracepoint.

      ext4: optimize orphan_list handling for ext4_setattr · 3d287de3
      Dmitry Monakhov authored
      Surprisingly chown() on ext4 is not SMP scalable operation. 
      Due to unconditional orphan_del(NULL, inode) in ext4_setattr()
      result in significant performance overhead because of global orphan
      mutex, especially in no-journal mode (where orphan_add() is noop).
      It is possible to skip explicit orphan_del if possible.
      Results of fchown() micro-benchmark in no-journal mode
      while (1) {
         fchown(fd, uid, gid);
         fchown(fd, uid + 1, gid + 1)

      proc_bus_pci_ioctl: remove pointless BKL usage · 0b2d8d9e
      Linus Torvalds authored
      The BKL was pushed into this function when it was converted to use the
      unlocked_ioctl interface, but nothing that the function touches is
      actually protected by the BKL.  So just remove the BKL entirely, so that
      we finally can get a realistic system build without the BKL being
      enabled at all.

      These functions have no need to be exported beyond file context.
      No functions needed to be moved for this commit; just some function

      (A similar patch was submitted by Eric Sandeen, but I wanted to handle
      code movement in separate patches to make sure code changes didn't
      accidentally get dropped.)
