Hi all, following bug is trying to workaround an error on ppc64le, where zram01.sh LTP test (there is also kernel selftest tools/testing/selftests/zram/zram01.sh, but LTP test got further updates) has often mem_used_total 0 although zram is already filled. Patch tries to repeatedly read /sys/block/zram*/mm_stat for 1 sec, waiting for mem_used_total > 0. The question if this is expected and should be workarounded or a bug which should be fixed. REPRODUCE THE ISSUE Quickest way to install only zram tests and their dependencies: make autotools && ./configure && for i in testcases/lib/ testcases/kernel/device-drivers/zram/; do cd $i && make -j$(getconf _NPROCESSORS_ONLN) && make install && cd -; done Run the test (only on vfat) PATH="/opt/ltp/testcases/bin:$PATH" LTP_SINGLE_FS_TYPE=vfat zram01.sh Petr Vorel (1): zram01.sh: Workaround division by 0 on vfat on ppc64le .../kernel/device-drivers/zram/zram01.sh | 27 +++++++++++++++++-- 1 file changed, 25 insertions(+), 2 deletions(-) -- 2.38.0
