Subject: [PATCH] bcachefs: WARNING in bch2_trans_srcu_unlock
Author: cam.alvarez.i@xxxxxxxxx
#syz test
bch2_extent_fallocate should not return -BCH_ERR_transaction_restart_nested when there are no buckets available.
Returning -BCH_ERR_transaction_restart_nested causes the sector allocation to retry even if there's no space available.
