      locking: Convert raw_spinlock to arch_spinlock · 445c8951
      Thomas Gleixner 提交于
      The raw_spin* namespace was taken by lockdep for the architecture
      specific implementations. raw_spin_* would be the ideal name space for
      the spinlocks which are not converted to sleeping locks in preempt-rt.
      
      Linus suggested to convert the raw_ to arch_ locks and cleanup the
      name space instead of using an artifical name like core_spin,
      atomic_spin or whatever

      locking: Reorder functions in spinlock.c · b7b40ade
      Thomas Gleixner 提交于
      Separate spin_lock and rw_lock functions. Preempt-RT needs to exclude
      the rw_lock functions from being compiled. The reordering allows to do
      that with a single #ifdef.

      udf: Avoid IO in udf_clear_inode · 2c948b3f
      Jan Kara 提交于
      It is not very good to do IO in udf_clear_inode. First, VFS does not really
      expect inode to become dirty there and thus we have to write it ourselves,
      second, memory reclaim gets blocked waiting for IO when it does not really
      expect it, third, the IO pattern (e.g. on umount) resulting from writes in
      udf_clear_inode is bad and it slows down writing a lot.
      
      The reason why UDF needed to do IO in udf_clear_inode is that UDF standard
      mandates extent length to exactly match inode size. But when we allocate
      extents to a file or directory, we don't really know what exactly the final
      file size will be and thus temporarily set it to block boundary and later
      truncate it to exact length in udf_clear_inode. Now, this is changed to
      truncate to final file size in udf_release_file for regular files. For
      directories and symlinks, we do the truncation at the moment when learn
      what the final file size will be.

      Jan Kara 提交于
      Some disks do not contain VAT inode in the last recorded block as required
      by the standard but a few blocks earlier (or the number of recorded blocks
      is wrong). So look for the VAT inode a bit before the end of the media.

      Global variable declarations must match the definitions in section attributes
