LU-5396: use gfp_t for gfp mask, instead of (unsigned) int

This fixes sparse warnings, such as:

  .../echo.c:670:62: warning: incorrect type in initializer
                              (different base types)
  .../echo.c:670:62:    expected int [signed] gfp_mask
  .../echo.c:670:62:    got restricted gfp_t

gfp_t was introduced in 2.6.14 (end of 2005), so that should
work all recent distributions.

Besides using gfp_t, there is no code change.

Add a new set of llapi routines for interacting with file layouts that

Define an opaque struct llapi_layout to abstract the layout of a

following documented functions are added the liblustreapi public

  llapi_layout_alloc - allocate a new layout
  llapi_layout_free - free memory allocated for a layout
  llapi_layout_file_create - create new file with given layout
  llapi_layout_file_open - open or create a file with given layout
  llapi_layout_get_by_path - get file layout given a path
  llapi_layout_get_by_fd - get file layout given a file descriptor
  llapi_layout_get_by_fid - get file layout given a Lustre FID
  llapi_layout_ost_index_get - get OST index associated with a stripe
  llapi_layout_ost_index_set - set OST index associated with a stripe
  llapi_layout_pattern_get - get RAID pattern of a layout
  llapi_layout_pattern_set - set RAID pattern of a layout
  llapi_layout_pool_name_get - get pool name of a layout
  llapi_layout_pool_name_set - set pool name of a layout
  llapi_layout_stripe_count_get - get stripe count of a layout
  llapi_layout_stripe_count_set - set stripe count of a layout
  llapi_layout_stripe_size_get - get stripe size of a layout
  llapi_layout_stripe_size_set - set stripe size of a layout

The layouts are read and written using fgetxattr() and fsetxattr()
instead of ioctl() to make it easier for architectures like Blue Gene
to function-ship the system calls.

LU-5208 tests: inject failure on the proper OST

The old test scripts assumed that the file created by the MDS2 will
be striped to the OST2 and OST1, but such assumption is wrong. When
the OSTs reside on different OSS nodes, the sanity-lfsck test_18c

LU-5428 libcfs: false alarm of libcfs watchdog

lc_watchdog_disable will not delete kernel timer, benefit of this
is no overhead of del_timer in each serivce loop, however, there
is a corner case that lc_watchdog_touch can race with lcw_cb when
service thread is actually idle:

1. service thread armed a timer before processing request, after
   it handled request, it called lc_watchdog_disable() and set
   lc_watchdog as disabled, but kernel timer is still outstanding.
2. service thread slept for many seconds because there is no
   request to handle
3. it's waken up by incoming request
4. it called lc_watchdog_touch and set watchdog status to enabled.
   now because timer is still alive, if timer is expired right
   before cfs_timer_arm(), then lcw_cb will set a disabled watchdog
   as "expired", which is wrong.
5. the next call of lc_watchdog_disable will complain for expired
   watchdog.

There are two options to fix this issue:
1. always del_timer in lc_watchdog_disable, however, it may increase
   system overhead when service threads are busy.
2. set watchdog as "enabled" after cfs_timer_arm, so there is no
   window for lcw_cb to see false status of watchdog.

This patch chooses the second approach to fix the problem

What is interesting here, is that we call log_wait_commit, from
within wait_for_space, but we are still holding the checkpoint_mutex
as it surrounds mostly the whole of wait_for_space.  And then, as we
are waiting, journal_commit_transaction can run, and if the
JBD2_FLUSHED bit is set, then we will also try to take the same
checkpoint_mutex.

It seems that we need to drop the checkpoint_mutex while sitting in
jbd2_log_wait_commit, if we want to guarantee that progress can be
made by jbd2_journal_commit_transaction().  There does not seem to be
anything preempt-rt specific about this, other then perhaps increasing
the odds of it happening.

LU-5434 mdd: disregard empty POSIX ACLs

Some files may have a POSIX ACL consisting of only a struct
posix_acl_xattr_header, resulting in unexpected permission errors.
Update mdd_check_acl() to return -EAGAIN when such ACLs are
encountered so the caller falls back to standard UNIX
permissions.

These empty ACLs originate from tools like cp. In some cases (e.g.
'cp -rp') just POSIX_ACL_XATTR_VERSION is given as the value of the
system.posix_acl_default extended attribute.  Lustre accepts and
stores this value on disk, and the bad default ACL then propagates
from directories to newly created directory entries.  Separate
patches will prevent the storage of these bad ACLs.  This patch
mitigates problems caused by the ones already stored.

Other minor updates:
- Use the kernel function posix_acl_xattr_count() to count the
  number of ACL entries.
- Convert remainder of mdd_check_acl() to TAB indentation.

LU-5415 ldlm: high load because of negative timeout

When the time of LRU resizing exceeds waiting period of
recalculation, the ldlm daemon will keep on resizing without any
interval of rest. That will cause high CPU load.

This patch fixes the problem by setting the recalculation timestamp
after LRU resizing finishes rather than before it. What is more, an
interval of one second is enforced between each recalculation.

long. Remove the headers posix-types.h and posix-wordsize.h. This
fixes two problems:

  1) Use of the LP*64 macros may make lustre headers unusable when
     config.h is not included (like when the headers are used out of
     tree).

  2) Some platforms (like powerpc64) define __u64 to be unsigned long
     in the kernel and unsigned long long in userspace. This means
     that a single autoconf test cannot be used to determine how to
     define the terrible LP*64 macros.

Imaginary ports of Lustre to non-Linux platforms may handle this
change by adding linux/types.h somewhere in their include path and
putting the right typedefs and defines therein.

LU-4656 tests: Add MOUNT_FLAGS variable and rename MOUNTOPT

This patch adds a MOUNT_FLAGS variable which can be set to any extra
flags to the mount command, such as "-n".  MOUNTOPT was renamed to
MOUNT_OPTS to reflect that is a list of options. It should now contain
just a comma-separated list of mount options which will be passed to
the mount command as "-o $MOUNT_OPTS".  MOUNT_OPTS should not include
the "-o" anymore.

MOUNT_FLAGS was added to the mount commands and output messages in
zconf_mount and zconf_mount_clients in test-framework.sh.  MOUNT_OPTS
was prepended with the "-o" before being passed to the mount command.
MOUNT_FLAGS was given an empty default value in cfg/local.sh, and some
short documentation was added above MOUNT_OPTS and MOUNT_FLAGS.  Any
place which called zconf_mount or zconf_mount_clients was updated to
pass the mount options without the "-o".

All code which added an option to MOUNT_OPTS was updated to add the
option correctly, with a comma only if necessary.  Wherever possible,
the new mount options were passed to zconf_mount* to avoid modifying
global state.  In som_mode_switch, som_preview was removed from the
options correctly, removing a comma if necessary.

Two lines in test_132 were also edited to use "lctl get_param -n"
instead of piping the output of "lctl get_param" through an awk
command.

Test-Parameters:     envdefinitions=MOUNT_OPTS=user_xattr,MOUNT_FLAGS="-o flock"

LU-3660 acl: support mount option "noacl" for zfs

zfs parse mount option in zpl layer, but osd-zfs calls dmu
directly, since ldiskfs parse "noacl" at mount time, osd-zfs
should do the same in osd_mount().

Similar to ldiskfs, osd-zfs should check whether ACL is enabled
for ACL operations, if not -EOPNOTSUPP is returned.

add sanity test 103b for "noacl" mount option.
