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. 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 ltp/fsstress.c | 197 ++++++++++++++++++++++++++++++++++++++++---------- tests/generic/579 | 56 ++++++++++++++ tests/generic/579.out | 2 + tests/generic/group | 1 + 4 files changed, 217 insertions(+), 39 deletions(-) create mode 100755 tests/generic/579 create mode 100644 tests/generic/579.out -- 1.8.3.1
