[LU-10517] setting llite.*.checksum_pages doesn't actually work

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Severity: 3

Description

The callers and handlers of obd_set_info_async(..., KEY_CHECKSUM, sizeof(val), &val, ...) are not in agreement about what type should be used for val. As a result of this disagreement setting llite.*.checksum_pages doesn't actually work:

# lctl set_param llite.*.checksum_pages=0
llite.lustre-ffff88007bf5e800.checksum_pages=0
# dmesg | tail -1
[22161.753228] Lustre: 13201:0:(lproc_llite.c:591:ll_checksum_seq_write()) Failed to set OSC checksum flags: -22
