Re: [LTP] [PATCH v4 3/7] syscalls/swapon03: use tst_max_swapfiles() and GET_USED_SWAPFILES() api

[Petr Vorel <pvorel@suse.cz>]

Hi Xu,

I see swapon03 failures on aarch64 and ppc64le on SLES and openSUSE after this commit.

Here is timeout after 31s:

### TEST swapon03 COMPLETE >>> 2.

I tried to run with .max_runtime = 60, but even then it fails after 1m 30s:

I'm trying with LTP_TIMEOUT_MUL=3.

BTW there is still broken swapoff01 on master on ppc64le which I reported [1]:
libswap.c:153: TBROK: Failed to create swapfile
(obviously no change in this patchset)

But I'll ping Li separately.

Kind regards,
Petr
