It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

Start the process of\n migrating users from the single-threaded daemon-based approach to\n the multi-threaded request-key based approach.\n\n - NFSv4.1 implementation id.\n\n Allows the NFSv4.1 client and server to mutually identify each\n other for logging and debugging purposes.\n\n - Support the \u0027vers\u003d4.1\u0027 mount option for mounting NFSv4.1 instead of\n having to use the more counterintuitive \u0027vers\u003d4,minorversion\u003d1\u0027.\n\n - SUNRPC tracepoints.\n\n Start the process of adding tracepoints in order to improve\n debugging of the RPC layer.\n\n - pNFS object layout support for autologin.\n\n Important bugfixes include:\n\n - Fix a bug in rpc_wake_up/rpc_wake_up_status that caused them to\n fail to wake up all tasks when applied to priority waitqueues.\n\n - Ensure that we handle read delegations correctly, when we try to\n truncate a file.\n\n - A number of fixes for NFSv4 state manager loops (mostly to do with\n delegation recovery).\"\n\n* tag

This thing registers itself with \"poll\" file operation and thus\nhas a reference to pipe wait queue. This leads to oopses on destroying eventfd\nafter NFS umount (like rpc_idmapd do) since not pipe data left to the point\nalready.\nThe solution is to wait queue from pipe data to internal RPC inode data.
