When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which
also depends on the modules number in Makefile. The related information
in "scripts/Makefile.lib" line 94:

  # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will
  # end up in (or would, if it gets compiled in)
  # Note: Files that end up in two or more modules are compiled without the
  #       KBUILD_MODNAME definition. The reason is that any made-up name would
  #       differ in different configs.

For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in
one line, so cause compiling issue. And 'uaccess.h' is a common shared
header (not specially for drivers), so use pr_devel() instead of is OK.

Most callers of that functions acqure the mutex by themselves and

i.e we have an unavoidable double lock.

The patch proposes to resolve the issue by making sure that
ufs_{new,free}_inode() are not called with the mutex held.

 "The fixes all address recently discovered data corruption issues.

  with page invalidation (exposed by millions of fsx operations) failing
  due to dirty buffers beyond EOF.

  Finally, the collapse_range code could also cause problems due to
  racing writeback changing the extent map while it was being shifted
  around.  The commits for that problem are simple mitigation fixes that
  prevent the problem from occuring.  A more robust fix for 3.18 that
  addresses the underlying problem is currently being worked on by
  Brian.

The update_walltime() code works on the shadow timekeeper to make the
seqcount protected region as short as possible. But that update to the
shadow timekeeper does not update all timekeeper fields because it's
sufficient to do that once before it becomes life. One of these fields
is tkr.base_mono. That stays stale in the shadow timekeeper unless an
operation happens which copies the real timekeeper to the shadow.

The update function is called after the update calls to vsyscall and
pvclock. While not correct, it did not cause any problems because none
of the invoked update functions used base_mono.

commit cbcf2dd3 (x86: kvm: Make kvm_get_time_and_clockread()
nanoseconds based) changed that in the kvm pvclock update function, so
the stale mono_base value got used and caused kvm-clock to malfunction.

Put the update where it belongs and fix the issue.

The reason this is needed is that starting with 3.15 kernel, due to
Theodore Ts'o's commit 02b9984d ("fs: push sync_filesystem() down to
the file system's remount_fs()"), all file systems that have dirty data
to be written out need to call sync_filesystem() from their
->remount_fs() method when remounting read-only.

As this is now a generically required function rather than an internal
only function it should be EXPORT_SYMBOL() so that all file systems can
call it.
