Subject: bcachefs: Don't invalidate open buckets
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=84ddb8b98e674c0d052dd56a406efc5275c9508a;p=linux.git

bcachefs: Don't invalidate open buckets

Like bch2_trans_mark_bucket(), we shouldn't be incrementing a bucket gen
while it's still open - erasure coding was hitting this.
