Subject: Added p_nextlock entry to separate queueing for a lock from queueing
X-Git-Tag: cvs/glibc_2-1-2~313
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4d3a2ae38462563844bba13ed159d7150f50c0e9;p=thirdparty%2Fglibc.git

Added p_nextlock entry to separate queueing for a lock from queueing
for a CV (sometimes a thread queues on a lock to serialize removing
itself from a CV queue).
