Subject: [PATCH] selinux: Remove load size limit
Date: Sat, 21 Sep 2019 09:57:15 +0800 [thread overview]
Message-ID: <1569031035-12354-1-git-send-email-zhang.lin16@zte.com.cn> (raw)
Load size was limited to 64MB, this was legacy limitation due to vmalloc()
which was removed a while ago.
Limiting load size to 64MB is both pointless and affects real world use
cases.
