      The generic segment check code now returns a count of the number of
      bytes in the iovec, so we don't need to roll our own anymore.

      xfs: make largest supported offset less shouty · 32972383
      Dave Chinner authored
      XFS_MAXIOFFSET() is just a simple macro that resolves to
      mp->m_maxioffset. It doesn't need to exist, and it just makes the
      code unnecessarily loud and shouty.
      
      Make it quiet and easy to read.

      xfs: m_maxioffset is redundant · d2c28191
      Dave Chinner authored
      The m_maxioffset field in the struct xfs_mount contains the same
      value as the superblock s_maxbytes field. There is no need to carry
      two copies of this limit around, so use the VFS superblock version.

      xfs: xfs_vm_writepage clear iomap_valid when !buffer_uptodate (REV2) · 7d0fa3ec
      Alain Renaud authored
      On filesytems with a block size smaller than PAGE_SIZE we currently have
      a problem with unwritten extents.  If a we have multi-block page for
      which an unwritten extent has been allocated, and only some of the
      buffers have been written to, and they are not contiguous, we can expose
      stale data from disk in the blocks between the writes after extent
      conversion.
      
      Example of a page with unwritten and real data.
      buffer  content
      0       empty  b_state = 0
      1       DATA   b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten
      2       DATA   b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten
      3       empty  b_state = 0
      4       empty  b_state = 0
      5       DATA   b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten
      6       DATA   b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten
      7       empty  b_state = 0
      
      Buffers 1, 2, 5, and 6 have been written to, leaving 0, 3, 4, and 7
      empty.  Currently buffers 1, 2, 5, and 6 are added to a single ioend,
      and when IO has completed, extent conversion creates a real extent from
      block 1 through block 6, leaving 0 and 7 unwritten.  However buffers 3
      and 4 were not written to disk, so stale data is exposed from those
      blocks on a subsequent read.
      
      Fix this by setting iomap_valid = 0 when we find a buffer that is not
      Uptodate.  This ensures that buffers 5 and 6 are not added to the same
      ioend as buffers 1 and 2.  Later these blocks will be converted into two
      separate real extents, leaving the blocks in between unwritten.

      x86, x32, ptrace: Remove PTRACE_ARCH_PRCTL for x32 · bad1a753
      H.J. Lu authored
      When I added x32 ptrace to 3.4 kernel, I also include PTRACE_ARCH_PRCTL
      support for x32 GDB  For ARCH_GET_FS/GS, it takes a pointer to int64.  But
      at user level, ARCH_GET_FS/GS takes a pointer to int32.  So I have to add
      x32 ptrace to glibc to handle it with a temporary int64 passed to kernel and
      copy it back to GDB as int32.  Roland suggested that PTRACE_ARCH_PRCTL
      is obsolete and x32 GDB should use fs_base and gs_base fields of
      user_regs_struct instead.
      
      Accordingly, remove PTRACE_ARCH_PRCTL completely from the x32 code to
      avoid possible memory overrun when pointer to int32 is passed to
      kernel.

      mtd: block2mtd: fix recursive call of mtd_writev · 2e24e32e
      Gabor Juhos authored
      The 'mtd_writev' interface calls the function assigned
      to the '_write' field of a given mtd device if that is
      not NULL. The block2mtd driver sets the '_writev' field
      to the 'mtd_writev' function itself and thus causes a
      endless loop.
      
      This is caused by 1dbebd32
      (mtd: harmonize mtd_writev usage).
      
      Remove the assignment from the block2mtd driver to fix the
      issue.
