if (sci->sc_stage.flags & NILFS_CF_SUFREED) {
err = nilfs_sufile_cancel_freev(nilfs->ns_sufile,
sci->sc_freesegs,
sci->sc_nfreesegs,
NULL);
WARN_ON(err); /* do not happen */
+ sci->sc_stage.flags &= ~NILFS_CF_SUFREED;
}
I see adding the code of clear NILFS_CF_SUFREED flag in the patch.
But nilfs_segctor_abort_construction() contains likewise code:
1727 if (sci->sc_stage.flags & NILFS_CF_SUFREED) {
1728 ret = nilfs_sufile_cancel_freev(nilfs->ns_sufile,
1729 sci->sc_freesegs,
1730 sci->sc_nfreesegs,
1731 NULL);
1732 WARN_ON(ret); /* do not happen */
1733 }
Maybe, this code needs in flag clearing too?
Anyway, I can see setting this flag and cannot see clearing
of it. Andreas suggests to clear this flag in the patch.
Is logic of setting/clearing this flag fully correct?
With the best regards,
Vyacheslav Dubeyko.
