selftests: ublk: replace assert() with ublk_assert()

2026-01-23T03:05:41Z

Replace assert() with ublk_assert() since it is often triggered in daemon, and we may get nothing shown in terminal. Add ublk_assert(), so we can log something to syslog when assert() is triggered. Signed-off-by: Ming Lei Signed-off-by: Jens Axboe

selftests: ublk: support non-O_DIRECT backing files

2026-01-12T16:16:38Z

A subsequent commit will add support for using a backing file to store integrity data. Since integrity data is accessed in intervals of metadata_size, which may be much smaller than a logical block on the backing device, direct I/O cannot be used. Add an argument to backing_file_tgt_init() to specify the number of files to open for direct I/O. The remaining files will use buffered I/O. For now, continue to request direct I/O for all the files.
