Data corruption is possible if cp(coreutils) uses FIEMAP to obtain
data holes in shared file, since there could be dirty cache on
other clients which hasn't been flushed back.
To ensure all the dirty on remote clients being flushed back on
fiemap ioctl, we'd acquire ldlm lock on server side for fiemap,
unless the local client (which invoke fiemap) has cached lock.

In order to avoid compatibility issues with older ChangeLog consumers,
change the new CL_LAYOUT record to use the value previously assigned
to CL_IOCTL. The CL_IOCTL type was never used anywhere, and it didn't
really make any sense as a ChangeLog record, since it could really
mean anything at all.
The changelog_show_cb() function is renamed to changelog_kkuc_cb(),
since it is really about consuming the ChangeLog and passing it up to
the kernel-user-coms interface. At some point we should consider to
implement a DBUS-based ChangeLog interface as well.
The changelog_kkuc_cb() "sanity check" on cr_type was removed, since
there is no reason the client kernel needs to know every record type
that is being passed to userspace. It is up to the client tool to
determine what records that it can process.

The usb3503 driver sleeps a flat 100ms when resetting the chip, with a

This patch reduces the sleep to the 4ms initialization delay that the
chip itself actually requires (as per its data sheet). If certain boards
require more time to set up the reference clock, they should change this
through local patches or add a proper, configurable synchronization

This version has one more correction: the vmalloc calls are replaced
by __vmalloc calls to preserve the GFP_NOFS flag.
When GFS2's directory management code allocates buffers for a
directory hash table, if it can't get the memory it needs, it
currently gives a bad return code. Rather than giving an error,
this patch allows it to use virtual memory rather than kernel
memory for the hash table. This should make it possible for
directories to function properly, even when kernel memory becomes
very fragmented.
