Subject: [IA64] Allow salinfo_decode to detect signals on read
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=05f70395c642bed0300bc1955bfa8c0f93de2bc2;p=openwrt%2Fstaging%2Fblogic.git

[IA64] Allow salinfo_decode to detect signals on read

Return -EINTR instead of -ERESTARTSYS when signals are delivered during
a blocked read of /proc/sal/*/event.  This allows salinfo_decode to
detect signals when it is blocked on a read of those files.
