Revision 1.13, Fri May 19 04:16:20 2006 UTC (11 years, 5 months ago) by mvalluri
Branch: MAIN
Changes since 1.12: +77 -0
lines
1) Edits to avoid using static memory buffers (Makefile, attr_repair.c,
dir.c, init.c)
2) Eliminate unused static variable use in scan.c + loop counter
check optimization.
1) Initialize thread-specific buffers (attr_freemap, dir_freemap, dirbuf).
2) Increase rlim_max and rlim_cur to RLIM_INFINITY
