Problem Description:

(1018517) Corrected call to vol_dereserve() with device name
	  as argument.
(1029539) Reverted VX_GET_NINODE back to 57 by switching it with
6305689 (1042499) fsync() times increase as file size grows on
	  VxFS even with few dirty pages VMODSORT.
(1048439) Update vx_logbuf_clean(). Move VX_DELAY(1) to later
	  position after releasing fs_logclean_slk lock.
(1053586) Added a check for the ownership of a locked thread
	  before trying to get the thread's ownership.
(1073275) Introduce a new field (valid) in dotdot_list to capture
	  if there is a valid parent. The new field exists in both
	  parent's databases and their attributes area. With this fix,
	  fsck can detect any invalid attribute entry.
(1074982) Remove VX_DELAY for performance gains.
(1075102) Need a better way to tell if a thread is a nfs
	  thread (Solaris).
(1079791) fsck log replay extremely slow.
6566674 (1087773) VxFS Global mount points within Sun Cluster are
	  not working under Sun Cluster on x86 platform.
(1087804) Fixed an issue in which the correct file system was not
	  always passed to vx_device_lookup if the I/O failed to
	  the snapped file system.
(1090585) Updated vx_read1() to invalidate entrie file that is
	  accessed via fdd, before and after doing I/O request.
(1090587) ACLs inherited from default ACLs allow greater
	  permission than requested in some cases.
(1093682) Resolve large extent file system hang issue.
(1096470) Added a check for the validity of a file system pointer
	  before accessing the fields in a file system structure.
	  This is needed because a file system structure may not
	  exist at this point because of a clean umount.
(1100675) Fixed an issue that if run_replay() returned before the
	  calling process_frees(), then replay_done() might have
	  tried to free memory that had not been allocated.
(993020) Introduce VX_CFS_IRWLOCKEOF and VX_CFS_SIZEVALID flags.
	  Updated vx_get_inodedata() to skip taking IGLOCK update
	  for regular file of nomtime mount when VX_CFS_SIZEVALID
	  flag is set. Also adjust flags VX_CFS_CFLAGS_MASK.

Patch Installation Instructions:

For the Solaris 10 release, refer to the online manual pages for
instructions on using 'patchadd' and 'patchrm' scripts provided with
Solaris.  Any other special or non-generic installation instructions
should be described below as special instructions.  The following
example installs a patch to a standalone machine:

       example# patchadd /var/spool/patch/110434-07

The following example removes a patch from a standalone system:

       example# patchrm 104945-02

For additional examples please see the appropriate manual pages.

Special Install Instructions:

Sun introduced a page ordering vnode optimization in Solaris 9 and 10.
The optimization includes a new vnode flag, VMODSORT, which when turned on
indicates that the Virtual Memory (VM) should maintain the v_pages list
in an order depending on if a page is modified or unmodified.

Veritas File System (VxFS) can now take advantage of that flag,
which can result in significant performance improvements on operations
that depend on flushing, such as fsync.

This optimization requires that Sun BugID's 6393251 and 6538758 be fixed
in the kernel release on which this patch is being installed.
Enabling VxFS VMODSORT functionality without the correct OS kernel patches
can result in data corruption.

Required operating system patches:

     (Solaris 10 x86)
     125101-10 Kernel Update patch

To enable VxFS VMODSORT functionality, the following line must be added
to the /etc/system file after the vxfs forceload:

        set vxfs:vx_vmodsort=1  * enable vxfs vmodsort

To disable VxFS VMODSORT functionality, the following line must be added
to the /etc/system file after the vxfs forceload:

        set vxfs:vx_vmodsort=0  * disable vxfs vmodsort

You need to use the shutdown command to reboot the system after patch
installation or de-installation:

     shutdown -g0 -y -i6
