SUMMARY OF INCIDENTS FIXED BY THE PATCH

Patch ID: 6.2.0.100
* 3703631 (3615043) Data loss when writing to a file while dalloc is on.
* 3723334 (3723336) On RHEL 6.6, umount(8) system call hangs if an application is watching for inode

DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: 6.2.0.100

* 3703631 (Tracking ID: 3615043)

SYMPTOM:
At times, while writing to a file, data could be missed.

DESCRIPTION:
While writing to a file when delayed allocation is on, Solaris could dishonour
the NON_CLUSTERING flag and 
cluster pages beyond the range for which we have issued the flushing, leading to
data loss.

RESOLUTION:
Make sure we clear the flag and flush the exact range, in case of dalloc.

* 3723334 (Tracking ID: 3723336)

SYMPTOM:
On RHEL 6.6, umount(8) system call hangs if an application is watching for inode
events using inotify(7) APIs.

DESCRIPTION:
On RHEL 6.6, additional counters were added in the super block to track inotify
watches, these new counters were not implemented in VxFS.
Hence while doing umount, the operation hangs until the counter in the
superblock drops to zero, which would never happen since they are not handled in
VXFS.

RESOLUTION:
Code is modified to handle additional counters added in RHEL6.6.
