X-Git-Tag: man-pages-5.09~178
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2c1b51b14b5de6b7c2181ae363c325eaf3228f81;p=thirdparty%2Fman-pages.git

epoll_ctl.2: epoll instances can be nested to a maximum depth of 5

This limit appears to be an off-by-one count against
EP_MAX_NESTS (4).

Verified by experiment.
