      Btrfs: avoid sleeping in verify_parent_transid while atomic · b9fab919
      Chris Mason 提交于
      verify_parent_transid needs to lock the extent range to make
      sure no IO is underway, and so it can safely clear the
      uptodate bits if our checks fail.
      
      But, a few callers are using it with spinlocks held.  Most
      of the time, the generation numbers are going to match, and
      we don't want to switch to a blocking lock just for the error
      case.  This adds an atomic flag to verify_parent_transid,
      and changes it to return EAGAIN if it needs to block to
      properly verifiy things.

      TTY: pdc_cons, fix regression in close · 49a5f3cf
      Jiri Slaby 提交于
      The test in pdc_console_tty_close '!tty->count' was always wrong
      because tty->count is decremented after tty->ops->close is called and
      thus can never be zero. Hence the 'then' branch was never executed and
      the timer never deleted.
      
      This did not matter until commit 5dd5bc40 ("TTY: pdc_cons, use
      tty_port").  There we needed to set TTY in tty_port to NULL, but this
      never happened due to the bug above.
      
      So change the test to really trigger at the last close by changing the
      condition to 'tty->count == 1'.
      
      Well, the driver should not touch tty->count at all.  It should use
      tty_port->count and count open count there itself.

      init: don't try mounting device as nfs root unless type fully matches · 377485f6
      Sasha Levin 提交于
      Currently, we'll try mounting any device who's major device number is
      UNNAMED_MAJOR as NFS root.  This would happen for non-NFS devices as
      well (such as 9p devices) but it wouldn't cause any issues since
      mounting the device as NFS would fail quickly and the code proceeded to
      doing the proper mount:
      
             [  101.522716] VFS: Unable to mount root fs via NFS, trying floppy.
             [  101.534499] VFS: Mounted root (9p filesystem) on device 0:18.
      
      Commit 6829a048102a ("NFS: Retry mounting NFSROOT") introduced retries
      when mounting NFS root, which means that now we don't immediately fail
      and instead it takes an additional 90+ seconds until we stop retrying,
      which has revealed the issue this patch fixes.
      
      This meant that it would take an additional 90 seconds to boot when
      we're not using a device type which gets detected in order before NFS.
      
      This patch modifies the NFS type check to require device type to be
      'Root_NFS' instead of requiring the device to have an UNNAMED_MAJOR
      major.  This makes boot process cleaner since we now won't go through
      the NFS mounting code at all when the device isn't an NFS root
      ("/dev/nfs").

      Jana Saout confirmed that this fixes the page faults he saw.
      
      His problem was triggered by ocfs2 and autofs symlink lookups, where the
      symlink allocation was at the end of a page.  But the deeper reason
      seems to be the use of Xen-PV, which is what then causes him to have all
      these unmapped pages, which is what then makes it a problem when the
      unaligned word-at-a-time code fetches data past the end of a page.

      md/bitmap: fix calculation of 'chunks' - missing shift. · b16b1b6c
      NeilBrown 提交于
      commit 61a0d80c "md/bitmap: discard CHUNK_BLOCK_SHIFT macro"
      replaced CHUNK_BLOCK_RATIO() by the same text that was
      replacing CHUNK_BLOCK_SHIFT() - which is clearly wrong.
      
      The result is that 'chunks' is often too small by 1,
      which can sometimes result in a crash (not sure how).
      
      So use the correct replacement, and get rid of CHUNK_BLOCK_RATIO
      which is no longe used.
