      mm: kill vma flag VM_CAN_NONLINEAR · 0b173bc4
      由 Konstantin Khlebnikov 提交于 
      Move actual pte filling for non-linear file mappings into the new special
vma operation: ->remap_pages().

Filesystems must implement this method to get non-linear mapping support,
if it uses filemap_fault() then generic_file_remap_pages() can be used.

Now device drivers can implement this method and obtain nonlinear vma support.

      9p: Reduce object size with CONFIG_NET_9P_DEBUG · 5d385153
      由 Joe Perches 提交于 
      Reduce object size by deduplicating formats.

Use vsprintf extension %pV.
Rename P9_DPRINTK uses to p9_debug, align arguments.
Add function for _p9_debug and macro to add __func__.
Add missing "\n"s to p9_debug uses.
Remove embedded function names as p9_debug adds it.
Remove P9_EPRINTK macro and convert use to pr_<level>.
Add and use pr_fmt and pr_<level>.

      fs/9p: check schedule_timeout_interruptible return value · a0ea787b
      由 Jim Garlick 提交于 
      In v9fs_file_do_lock() we need to check return value of
schedule_timeout_interruptible() and exit the loop when it
returns nonzero, otherwise the loop is not really interruptible
and after the signal, the loop is no longer throttled by
P9_LOCK_TIMEOUT.

      fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers · 02c24a82
      由 Josef Bacik 提交于 
      Btrfs needs to be able to control how filemap_write_and_wait_range() is called
in fsync to make it less of a painful operation, so push down taking i_mutex and
the calling of filemap_write_and_wait() down into the ->fsync() handlers.  Some
file systems can drop taking the i_mutex altogether it seems, like ext3 and
ocfs2.  For correctness sake I just pushed everything down in all cases to make
sure that we keep the current behavior the same for everybody, and then each
individual fs maintainer can make up their mind about what to do from there.
Thanks,

      9p: Include fsync support for 9p client · 7a4439c4
      由 M. Mohan Kumar 提交于 
      Implement the fsync in the client side by marking stat field values to 'don't touch' so that server may 
interpret it as a request to guarantee that the contents of the associated file are committed to stable 
storage before the Rwstat message is returned.

Without this patch, calling fsync on a 9p file results in "Invalid argument" error. Please check the attached 
C program.
