This patch series has one of the patches which fixes that. It also has couple of posix lock fixes as a result of lo_flush() related debugging. Vivek Goyal (3): virtiofsd: Set up posix_lock hash table for root inode virtiofsd: Disable posix_lock hash table if remote locks are not enabled virtiofsd: Check file type in lo_flush() tools/virtiofsd/passthrough_ll.c | 54 +++++++++++++++++++++++--------- 1 file changed, 39 insertions(+), 15 deletions(-) Tested-by: Laszlo Ersek
