| | | | | | | | | | | | | | | | | | | | | | | | | When mounting, in parallel, multiple loop devices (squashfs for the submitter's case), the following behavior can be observed: stat64(/path/to/image, {st_mode=S_IFREG|0644, st_size=4096, ...}) = 0 openat(AT_FDCWD, /path/to/image, O_RDWR|O_LARGEFILE) = 3 openat(AT_FDCWD, /dev/loop-control, O_RDWR|O_LARGEFILE|O_CLOEXEC) = 4 ioctl(4, LOOP_CTL_GET_FREE) = 12 close(4) = 0 openat(AT_FDCWD, /dev/loop12, O_RDWR|O_LARGEFILE) = 4 ioctl(4, LOOP_GET_STATUS64, {lo_offset=0, lo_number=12, lo_flags=LO_FLAGS_AUTOCLEAR, lo_file_name=/path/to/image, ...}) = 0 close(4) = 0 close(3) = 0 write(2, "mount: can't setup loop device\n", 31mount: can't setup loop device ) = 31 exit_group(0) = ? +++ exited with 0 +++ The ioctl LOOP_CTL_GET_FREE has resulted in the same result for a competing mount process. The subsequent ioctl LOOP_GET_STATUS64 fails, having succeeded for the competing mount process. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
