When encryption is enabled RPCs are encrypted just before being sent. The encryption requires allocating memory in the encoding pool. The current implementation in sptlrpc_enc_pool_get_pages() is deadlock-prone. Indeed, if there is no more free pages in the pool, all ptlrpcd threads can end up waiting in a queue, so there is no thread available to process other requests. It means client is not able to process replies from servers that yet contain last committed transno useful to release memory allocated by previous requests, including enc_pool pages. To fix this, in sptlrpc_enc_pool_get_pages(), do not make ptlrpcd threads wait in queue if encoding pool has already reached its maximum capacity. Instead, return -ENOMEM. If functions calling ptl_send_rpc() get -ENOMEM, then put back request in queue by moving it back to RQ_PHASE_NEW phase. As an optimization, do not call ptl_send_rpc() again for requests that already failed to allocate in the enc_pool, as long as there is not enough memory in the enc_pool to satisfy theirs needs. In /sys/fs/lustre/sptlrpc/encrypt_page_pools, add a new 'out of mem' stat to track how many requests fail to allocate memory in the enc_pool. Signed-off-by:

If the request is allowed to be sent during recovery, and it is not timeout yet, then we do not need to resend it in the final stage of recovery. Unnecessary resend will cause the bulk request to resend the request with different mbit, but same xid, and on the remote server side, it will drop such request with same xid, so it will never get the bulk in this case.

Atomically assign XIDs and put request and sending list so we can learn the lowest unreplied XID at any point. This allows to embed in every resquests the highest XID for which a reply has been received and does not have an unreplied lower-numbered XID.

Bits are set in bd_type to specify {put,get}{source,sink}{kvec,kiov} changed all instances in the code to access the union properly ASSUMPTION: all current code only works with KIOV and new DNE code to be added will introduce a different code path that uses IOVEC As part of the implementation buffer operations are added as callbacks to be defined by users of ptlrpc. This enables buffer users to define how to allocate and release buffers.

Pull x86 bugfix from Thomas Gleixner: "A single bugfix for the recent changes related to registering the boot cpu when this has not happened before prefill_possible_map(). The main problem with this change got fixed already, but we missed the case where the local APIC is not yet mapped, when prefill_possible_map() is invoked, so the registration of the boot cpu which has the APIC bit set in CPUID will explode.
