Then running fstests is exactly the same as other local filesystems - just set FSTYP=bcachefs Also see https://evilpiepirate.org/git/ktest.git/ for a tool for conveniently building kernel and running fstests inside a qemu VM. This patch also updates generic/441 to run the more thorough test on bcachefs, and generic/425 to not run on bcachefs (since bcachefs does not store xattrs in blocks) Signed-off-by: Kent Overstreet --- common/attr | 6 ++++++ common/config | 3 +++ common/quota | 4 ++-- common/rc | 11 +++++++++++ tests/generic/425 | 3 +++ tests/generic/441 | 2 +- 6 files changed, 26 insertions(+), 3 deletions(-) diff --git a/common/attr b/common/attr index 669909d600..42ceab9233 100644 --- a/common/attr +++ b/common/attr @@ -33,6 +33,9 @@ _acl_get_max() echo 506 fi ;; + bcachefs) + echo 251 + ;; *) echo 0 ;; @@ -273,6 +276,9 @@ pvfs2) 9p|ceph|nfs) MAX_ATTRVAL_SIZE=65536 ;; +bcachefs) + MAX_ATTRVAL_SIZE=1024 + ;; *) # Assume max ~1 block of attrs BLOCK_SIZE=`_get_block_size $TEST_DIR` diff --git a/common/config b/common/config index 1a26934985..ad1c9eb092 100644 --- a/common/config +++ b/common/config @@ -416,6 +416,9 @@ _mkfs_opts() btrfs) export MKFS_OPTIONS="$BTRFS_MKFS_OPTIONS" ;; + bcachefs) + export MKFS_OPTIONS=$BCACHEFS_MKFS_OPTIONS + ;; *) ;; esac diff --git a/common/quota b/common/quota index 32a9a55593..883a28a20d 100644 --- a/common/quota +++ b/common/quota @@ -17,7 +17,7 @@ _require_quota() _notrun "Installed kernel does not support quotas" fi ;; - gfs2|ocfs2) + gfs2|ocfs2|bcachefs) ;; xfs) if [ ! -f /proc/fs/xfs/xqmstat ]; then @@ -278,7 +278,7 @@ _check_quota_usage() VFS_QUOTA=0 case $FSTYP in - ext2|ext3|ext4|ext4dev|f2fs|reiserfs|gfs2) + ext2|ext3|ext4|ext4dev|f2fs|reiserfs|gfs2|bcachefs) VFS_QUOTA=1 quotaon -f -u -g $SCRATCH_MNT 2>/dev/null ;; diff --git a/common/rc b/common/rc index b18cf61e8a..a0aa7300dc 100644 --- a/common/rc +++ b/common/rc @@ -1065,6 +1065,9 @@ _scratch_mkfs_sized() fi export MOUNT_OPTIONS="-o size=$fssize $TMPFS_MOUNT_OPTIONS" ;; + bcachefs) + $MKFS_PROG -t $FSTYP -- $MKFS_OPTIONS --fs_size=$fssize --block_size=$blocksize $SCRATCH_DEV + ;; *) _notrun "Filesystem $FSTYP not supported in _scratch_mkfs_sized" ;; @@ -1133,6 +1136,9 @@ _scratch_mkfs_blocksized() ocfs2) yes | ${MKFS_PROG} -t $FSTYP -F $MKFS_OPTIONS -b $blocksize -C $blocksize $SCRATCH_DEV ;; + bcachefs) + ${MKFS_PROG} -t $FSTYP $MKFS_OPTIONS --block_size=$blocksize $SCRATCH_DEV + ;; *) _notrun "Filesystem $FSTYP not supported in _scratch_mkfs_blocksized" ;; @@ -1179,6 +1185,11 @@ _repair_scratch_fs() fi return $res ;; + bcachefs) + # With bcachefs, if fsck detects any errors we consider it a bug and we + # want the test to fail: + _check_scratch_fs + ;; *) local dev=$SCRATCH_DEV local fstyp=$FSTYP diff --git a/tests/generic/425 b/tests/generic/425 index 51cbe1c67d..be2bc1b02e 100755 --- a/tests/generic/425 +++ b/tests/generic/425 @@ -30,6 +30,9 @@ _cleanup() # real QA test starts here _supported_fs generic + +[ $FSTYP = bcachefs ] && _notrun "bcachefs does not store xattrs in blocks" + _require_scratch _require_attrs _require_xfs_io_command "fiemap" "-a" diff --git a/tests/generic/441 b/tests/generic/441 index bedbcb0817..814387b2a9 100755 --- a/tests/generic/441 +++ b/tests/generic/441 @@ -40,7 +40,7 @@ case $FSTYP in btrfs) _notrun "btrfs has a specialized test for this" ;; - ext3|ext4|xfs) + ext3|ext4|xfs|bcachefs) # Do the more thorough test if we have a logdev _has_logdev && sflag='' ;; -- 2.32.0.rc0
