What is the meaning of XLOG_MIN_RECORD_BSIZE? (Missing a check?)

[Jan Tulak <jtulak@xxxxxxxxxx>]

Hi guys,

what is the meaning ofÂXLOG_MIN_RECORD_BSIZE inÂlibxfs/xfs_log_format.h?

It is not used anywhere. I thought it might be related to -l su/sunit option, but seeing tests with -l su=4096 (the macro is set to 16k), it looks more like a forgotten value.Â

There is no check for a minimal value, so I can do -l su=1 (or su=0). Are there some caveatâs (other than performance) with such a small value? Can it be that we are missing a check? BecauseÂ

XLOG_BIG_RECORD_BSIZE

â and XLOG_MAX_RECORD_BSIZE are used and the upper bound is limited.â..

âThanksâ.

Cheers,

Jan
