Subject: [PATCH v3 0/4] xfstests: add deadlock between the AGI and AGF with RENAME_WHITEOUT test
Date: Thu, 31 Oct 2019 14:41:45 +0800 [thread overview]
Message-ID: <cover.1572503039.git.kaixuxia@tencent.com> (raw)
Hi all,
There is ABBA deadlock bug between the AGI and AGF when performing
rename() with RENAME_WHITEOUT flag, so add test to check that whether
the rename() call works well. We add the renameat2 syscall support to
fsstress, and then reproduce the deadlock problem by using fsstress.
Changes for v3:
- Add ancestor-descendant relationship checks for two dirs
in RENAME_EXCHANGE.
- Rebase the patchset to the latest xfstests.
Changes for v2:
- Fix the xattr_count value of the original devnode in
RENAME_WHITEOUT.
- Fix the parent ids swap problem in RENAME_EXCHANGE.
- Add the necessary comments.
kaixuxia (4):
fsstress: show the real file id and parid in rename_f()
fsstress: add NOREPLACE and WHITEOUT renameat2 support
fsstress: add EXCHANGE renameat2 support
xfs: test the deadlock between the AGI and AGF with RENAME_WHITEOUT
