Revision 1.53, Tue Aug 8 15:32:10 2006 UTC (11 years, 2 months ago) by nathans.longdrop.melbourne.sgi.com
Branch: MAIN
Changes since 1.52: +3 -1
lines
Allow tools to use direct IO on Linux when reading from the device, if teh device supports it, and if the tools is OK with that (most are). Mainly for xfs_repair speedups, now that libxfs caches metadata buffers internally.
Merge of master-melb:xfs-cmds:26728a by kenmcd.
