Hi. There are discussions about deadlocks issue of ZFS on freebsd-current ML, starting from [1] last month. IIRC, at least some fixes (candidates?) are merged to main, but not yet to stable/14. Upcoming (aleready released? or still rc3?) OpenZFS 2.2-release seems to have most of them. So my 1st question is "Is there any plan to import vendor/openzfs/zfs-2.2-release into stable/14 BEFORE BRANCHING releng/14? And one more. timerfd is added at last-minutes BEFORE stable/14 is branched, and already have not-yet-MFC'ed fixes [2], [3], [4] and Differential revision D41600 on Phablicator [5] related to memory leaks and locks. Additionally, splitting out lib32 part to proper place is proposed as D41640 [6]. Both [5] and [6] are accepted but not yet landed. Also, D41641 [7] proposes namespace pollution adjustments. This can be optional? Memory leaks and improper locks can lead system to security issues or deadlocks, so it would be benefical if landed and MFC'ed BEFORE releng/14 branches. Is there any plan to do so? At least, existing deadlocks should be considered as SHOW-STOPPER and resolved. I myself am bitten by several deadlocks on poudriere full builds after upgrading base from stable/13 to stable/14, finally finished with increasing kern.maxvnodes after powercycle on each deadlock and continue. Thanks in advance!
