These are quota limits, not "default quotas". I'd suggest taht this whole set of structures need to be renamed as "quota limits". e.g struct xfs_quota_limits { xfs_qcnt_t hard; /* default hard limit */ xfs_qcnt_t soft; /* default soft limit */ time64_t time; /* limit for timers */ xfs_qwarncnt_t warn; /* limit for warnings */ }; Then we have qlim = xfs_qm_get_default_limits(q, xfs_dquot_type(dq)); > > > diff --git a/fs/xfs/xfs_dquot.c b/fs/xfs/xfs_dquot.c > index 2d6b50760962..6975c27145fc 100644 > --- a/fs/xfs/xfs_dquot.c > +++ b/fs/xfs/xfs_dquot.c > @@ -76,22 +76,22 @@ xfs_qm_adjust_dqlimits( > ASSERT(dq->q_id); > defq = xfs_get_defquota(q, xfs_dquot_type(dq)); > > - if (defq->bsoftlimit && !dq->q_blk.softlimit) { > - dq->q_blk.softlimit = defq->bsoftlimit; > + if (defq->dfq_blk.softlimit && !dq->q_blk.softlimit) { > + dq->q_blk.softlimit = defq->dfq_blk.softlimit; > prealloc = 1; > } > - if (defq->bhardlimit && !dq->q_blk.hardlimit) { > - dq->q_blk.hardlimit = defq->bhardlimit; > + if (defq->dfq_blk.hardlimit && !dq->q_blk.hardlimit) { > + dq->q_blk.hardlimit = defq->dfq_blk.hardlimit; > prealloc = 1; > } > - if (defq->isoftlimit && !dq->q_ino.softlimit) > - dq->q_ino.softlimit = defq->isoftlimit; > - if (defq->ihardlimit && !dq->q_ino.hardlimit) > - dq->q_ino.hardlimit = defq->ihardlimit; > - if (defq->rtbsoftlimit && !dq->q_rtb.softlimit) > - dq->q_rtb.softlimit = defq->rtbsoftlimit; > - if (defq->rtbhardlimit && !dq->q_rtb.hardlimit) > - dq->q_rtb.hardlimit = defq->rtbhardlimit; > + if (defq->dfq_ino.softlimit && !dq->q_ino.softlimit) > + dq->q_ino.softlimit = defq->dfq_ino.softlimit; > + if (defq->dfq_ino.hardlimit && !dq->q_ino.hardlimit) > + dq->q_ino.hardlimit = defq->dfq_ino.hardlimit; > + if (defq->dfq_rtb.softlimit && !dq->q_rtb.softlimit) > + dq->q_rtb.softlimit = defq->dfq_rtb.softlimit; > + if (defq->dfq_rtb.hardlimit && !dq->q_rtb.hardlimit) > + dq->q_rtb.hardlimit = defq->dfq_rtb.hardlimit; And all this turns into somthing much easier to read: .... if (qlim->ino.soft && !dq->q_ino.softlimit) dq->q_ino.softlimit = qlim->ino.soft; if (qlim->ino.hard && !dq->q_ino.hardlimit) dq->q_ino.hardlimit = qlim->ino.hard; .... I'll also suggest we don't need to check qlim values here. It could just be: if (!dq->q_ino.softlimit) dq->q_ino.softlimit = qlim->ino.soft; if (!dq->q_ino.hardlimit) dq->q_ino.hardlimit = qlim->ino.hard; > @@ -41,20 +41,18 @@ extern struct kmem_zone *xfs_qm_dqtrxzone; > */ > #define XFS_DQUOT_CLUSTER_SIZE_FSB (xfs_filblks_t)1 > > +struct xfs_def_qres { > + xfs_qcnt_t hardlimit; /* default hard limit */ > + xfs_qcnt_t softlimit; /* default soft limit */ > + time64_t timelimit; /* limit for timers */ > + xfs_qwarncnt_t warnlimit; /* limit for warnings */ > +}; As I implied above, this is a quota limits structure, not a "default quota" structure.

It just makes the code more verbose and harder to read. e.g. > diff --git a/fs/xfs/xfs_qm_syscalls.c b/fs/xfs/xfs_qm_syscalls.c > index 1b2b70b1660f..393b88612cc8 100644 > --- a/fs/xfs/xfs_qm_syscalls.c > +++ b/fs/xfs/xfs_qm_syscalls.c > @@ -502,8 +502,8 @@ xfs_qm_scall_setqlim( > dqp->q_blk.softlimit = soft; > xfs_dquot_set_prealloc_limits(dqp); > if (id == 0) { > - defq->bhardlimit = hard; > - defq->bsoftlimit = soft; > + defq->dfq_blk.hardlimit = hard; > + defq->dfq_blk.softlimit = soft; IMO, these sorts of changes decrease the reability of the code. I'd much prefer something like: if (id == 0) { - defq->bhardlimit = hard; - defq->bsoftlimit = soft; + qlim->blk.hard = hard; + qlim->blk.soft = soft; As it is still clear we are changing the hard block quota limits...
