Subject: tests: set shmmni to 32k
X-Git-Tag: v2.37-rc1~176
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a992cc0d98bc45581c3a9f7e216742c4b20fc875;p=thirdparty%2Futil-linux.git

tests: set shmmni to 32k

Linux kernel since 6730e6580177d13f4612767873cb5a533ad63c61 checks for
limits and kernel ipc/utils.h defines

 #define IPCMNI_SHIFT         15
 #define IPCMNI               (1 << IPCMNI_SHIFT)

it means 32768 (aka shortint max). Let's use it in our tests too to
avoid "Invalid argument" when write to /proc/sys/kernel/shmmni.
