btrfs-progs: Introduce a misc test for thread conflict in btrfs-convert
Current code of btrfs-convert have a bug of thread conflict, which caused invalid memory accessing between threads, and make program panic. This patch add a test item for above bug, as: # ./ [TEST] 001-btrfstune-features [TEST] 002-uuid-rewrite [TEST] 003-zero-log [TEST] 004-convert-thread-conflict failed: btrfs-convert /root/btrfsprogs/tests/test.img test failed for case 004-convert-thread-conflict # # cat misc-tests-results.txt ... ############### btrfs-convert /root/btrfsprogs/tests/test.img trans 7 running 5 ctree.c:363: btrfs_cow_block: Assertion `1` failed. btrfs-convert(btrfs_cow_block+0x92)[0x40acaf] btrfs-convert(btrfs_search_slot+0x1cb)[0x40c50f] btrfs-convert(btrfs_csum_file_block+0x20f)[0x41d83a] btrfs-convert[0x43422d] btrfs-convert[0x4342cd] btrfs-convert[0x4345ca] btrfs-convert[0x434767] btrfs-convert[0x435770] btrfs-convert[0x439748] btrfs-convert(main+0x13f8)[0x43b09d] /lib64/[0x335e01ecdd] btrfs-convert[0x407649] create btrfs filesystem: blocksize: 4096 nodesize: 16384 features: extref, skinny-metadata (default) creating btrfs metadata. creating ext2fs image file. failed: btrfs-convert /root/btrfsprogs/tests/test.img test failed for case 004-convert-thread-conflict # Note that this bug is not happened every time, especilly in slow device as loop(slow cpu with fast block device is likely to trigger). I set loop count to 20 to make bug happened in 90% tests. Suggested-by: David Sterba <> Signed-off-by: Zhao Lei <> Signed-off-by: David Sterba <>
