Look like these two refer to my recent work on rbd:
2019 const char *fname = "/sys/bus/rbd/remove_single_major";
2020 if (stat(fname, &sbuf)) {
2021 fname = "/sys/bus/rbd/remove";
2022 }
2023
2024 int fd = open(fname, O_WRONLY); <---
2025 if (fd < 0) {
This is not a TOCTOU as there is no race here, so technically
annotations are in order, but I'll redo it as two open()s instead.
Thanks,
