Date: Wed, 16 Dec 2020 10:47:24 +0530 From: Ritesh Harjani <riteshh@...ux.ibm.com> To: fstests@...r.kernel.org Cc: Eryu Guan <guan@...u.me>, linux-ext4@...r.kernel.org, linux-xfs@...r.kernel.org, anju@...ux.vnet.ibm.com, Ritesh Harjani <riteshh@...ux.ibm.com> Subject: [PATCHv2 1/2] common/rc: Add whitelisted FS support in _require_scratch_swapfile() Filesystems e.g. ext4 and XFS supports swapon by default and an error returned with swapon should be treated as a failure. Hence add ext4/xfs as whitelisted fstype in _require_scratch_swapfile() Signed-off-by: Ritesh Harjani <riteshh@...ux.ibm.com> --- v1->v2: Addressed comments from Eryu @[1] [1]: https://patchwork.kernel.org/project/fstests/cover/cover.1604000570.git.riteshh@linux.ibm.com/ common/rc | 20 ++++++++++++++++---- 1 file changed, 16 insertions(+), 4 deletions(-) diff --git a/common/rc b/common/rc index 33b5b598a198..635b77a005c6 100644 --- a/common/rc +++ b/common/rc @@ -2380,6 +2380,7 @@ _format_swapfile() { # Check that the filesystem supports swapfiles _require_scratch_swapfile() { + local fstyp=$FSTYP _require_scratch _require_command "$MKSWAP_PROG" "mkswap" @@ -2401,10 +2402,21 @@ _require_scratch_swapfile() # Minimum size for mkswap is 10 pages _format_swapfile "$SCRATCH_MNT/swap" $(($(get_page_size) * 10)) - if ! swapon "$SCRATCH_MNT/swap" >/dev/null 2>&1; then - _scratch_unmount - _notrun "swapfiles are not supported" - fi + # For whitelisted fstyp swapon should not fail. + case "$fstyp" in + ext4|xfs) + if ! swapon "$SCRATCH_MNT/swap" >/dev/null 2>&1; then + _scratch_unmount + _fail "swapon failed for $fstyp" + fi + ;; + *) + if ! swapon "$SCRATCH_MNT/swap" >/dev/null 2>&1; then + _scratch_unmount + _notrun "swapfiles are not supported" + fi + ;; + esac swapoff "$SCRATCH_MNT/swap" >/dev/null 2>&1 _scratch_unmount -- 2.26.2
