These are all the same shape: set up the pool to suspend on first write, then perform some write+sync operation. The pool should suspend, and the sync operation should respond according to the failmode= property. We test fsync(), msync() and two forms of write() (open with O_SYNC, and async with sync=always), which all take slightly different paths to zil_commit() and back. A helper function is included to do the write+sync sequence with mmap() and msync(), since I didn't find a convenient tool to do that. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc.
