jiffies should have enough resolution.
Definitely, they should have 16 or even 32 pages per mount. With 500K lockres, which is not so extreme on bigger FS, 16 pages mean hash chains of average length 61 on x86_64. It is not ideal but I guess it should be sufficient.
Any objections to increasing the default to 32 pages for 1.4? _______________________________________________ Ocfs2-devel mailing list [email protected] http://oss.oracle.com/mailman/listinfo/ocfs2-devel
