https://bugzilla.novell.com/show_bug.cgi?id=715854 https://bugzilla.novell.com/show_bug.cgi?id=715854#c4 --- Comment #4 from Andreas Jaeger 2011-09-03 19:49:44 UTC --- I've just reverted my patch and updated glibc in Base:System. SR#80804 is the submit request to openSUSE:Factory. Is any one hitting this running a 3.1 kernel? This is supposed to speedup some operations on 3.1 kernels (without it those would be slower) - and I guess the handling of older kernels is broken. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So, the number of right syscalls is important, not the number of total syscalls. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
