Description

Successive calls to libcfs_debug_dumplog() can occur with no delay between calls and can generate a very large number of log files and error messages like this over and over:

[2009-08-01 00:45:59][c2-0c1s1n0]LustreError: dumping log to /tmp/lustre-log.1249105560.4266
[2009-08-01 00:45:59][c2-0c1s1n0]LustreError: can't open /tmp/lustre-log.1249105560.4266 file: err -17
[2009-08-01 00:45:59][c2-0c1s1n0]LustreError: dumping log to /tmp/lustre-log.1249105560.4266

This proposed patch will make debug log file name more unique.
