Every xfs_btree_insert/delete caller expects overall only success
or failure, so these tests and mark_sick calls can be consolidated
into those functions themselves, with callchain tests and extra
"status" parameters removed.

xfs_btree_insert() validates its own status internally via the result
of xfs_btree_insrec(). When it returns 0 it guarantees the status value
is 1; on any error it returns a nonzero error and does not update the
status value, so on error the status value is meaningless and on success
the status value does not need to be tested.
This makes every instance of the 2nd test in this idiom:
if ((error = xfs_btree_insert(cnt_cur, &i)))
return error;
if (XFS_IS_CORRUPT(mp, i != 1)) {
xfs_btree_mark_sick(cnt_cur);
return -EFSCORRUPTED;
}
unreachable on an error, and always false on success. The mark_sick and
error return cannot be reached, so remove all that.

xfs_refcount_insert() simply returns the error and status from
xfs_btree_insert, which has already validated the insert or returned
an error.
This makes every instance of the 2nd test in this idiom:
if ((error = xfs_refcount_insert(cnt_cur, &i)))
return error;
if (XFS_IS_CORRUPT(mp, i != 1)) {
xfs_btree_mark_sick(cnt_cur);
return -EFSCORRUPTED;
}
unnecessary/unreachable code. Remove them.

xfs_btree_insert and its callers now have no need for the status
parameter; either they return error = 0 / status = 1, or nonzero error
and status 0. No caller evaluates the status variable, so remove that
parameter from these functions.
As requested, convert all of the compound tests/assignments to discrete
lines.

From: Eric Sandeen @ 2026-10-16 19:29 UTC (permalink / raw)
To: linux-xfs; +Cc: cem, hch, dgc, Eric Sandeen
Unlike xfs_btree_insert(), xfs_btree_delete() does not validate its own
status return internally, so every caller open-codes the same check that
a record was actually deleted:
error = xfs_btree_delete(cur, &i);
if (error)
return error;
if (XFS_IS_CORRUPT(mp, i != 1)) {
xfs_btree_mark_sick(cur);
return -EFSCORRUPTED;
}
No caller expects or accepts i == 0; that is considered corruption in
every case.
Move this check into xfs_btree_delete, to mirror xfs_btree_insert's
behavior, so that xfs_btree_delete either returns error = 0 / status = 1,
or a nonzero error.
With that in place, remove the now-redundant i != 1 checks from all
callers, parallel to what was done earlier for xfs_btree_insert().

xfs_refcount_delete() simply returns the error and status from
xfs_btree_delete, which now validates the delete or returns an error.
This makes every instance of the 2nd test in this idiom:
error = xfs_refcount_delete(cur, &found_rec);
if (error)
goto out_error;
if (XFS_IS_CORRUPT(cur->bc_mp, found_rec != 1)) {
xfs_btree_mark_sick(cur);
error = -EFSCORRUPTED;
goto out_error;
}
unnecessary/unreachable code. Remove them.

xfs_btree_delete and its callers now have no need for the status
parameter; either they return error = 0 / status = 1, or nonzero error
and status 0. No caller evaluates the status variable, so remove that
parameter from these functions.
As requested, convert all of the compound tests/assignments to discrete
lines.
