With struct pid being dynamically\nallocated meant we could create the hash table entry when the pid was\nallocated and free the hash table entry when the pid was freed. Instead of\nplaying with the hash lists when ever a process would attach or detach to a\nprocess.\n\nFor myself the fact that it gave what my previous task_ref patch gave for free\nwith simpler code was a big win. The problem is that if you hold a reference\nto struct task_struct you lock in 10K of low memory. If you do that in a user\ncontrollable way like /proc does, with an unprivileged but hostile user space\napplication with typical resource limits of 1000 fds and 100 processes I can\ntrigger the OOM killer by consuming all of low memory with task structs, on a\nmachine wight 1GB of low memory.\n\nIf I instead hold a reference to struct pid which holds a pointer to my\ntask_struct, I don\u0027t suffer from that problem because struct pid is 2 orders\nof magnitude smaller. In fact struct pid is small enough that most other\nkernel data structures dwarf it, so simply limiting the number of referring\ndata structures is enough to prevent exhaustion of low memory.\n\nThis splits the current struct pid into two structures, struct pid and struct\npid_link, and reduces our number of hash tables from PIDTYPE_MAX to just one.\nstruct pid_link is the per process linkage into the hash tables and lives in\nstruct task_struct. struct pid is given an indepedent lifetime, and holds\npointers to each of the pid types.\n\nThe independent life of struct pid simplifies attach_pid, and detach_pid,\nbecause we are always manipulating the list of pids and not the hash table.\nIn addition in giving struct pid an indpendent life it makes the concept much\nmore powerful.\n\nKernel data structures can now embed a struct pid * instead of a pid_t and\nnot suffer from pid wrap around problems or from keeping unnecessarily\nlarge amounts of memory allocated.\n\nSigned-off-by: Eric W.

I think someone finally implemented atomic_inc_not_zero(\u0026count) to\nautomate the common case. Unfortunately this means you must special case the\nrcu access case.\n\nWhen data structures are only visible via rcu in a manner that is not\ndetermined by the reference count on the object (i.e. tasks are visible until\ntheir zombies are reaped) there is a much simpler technique we can employ.\nSimply delaying the decrement of the reference count until the rcu interval is\nover.\n\nWhat that means is that the proc code that looks up a task and later\nwants to sleep can now do:\n\nrcu_read_lock();\ntask \u003d find_task_by_pid(some_pid);\nif (task) {\n\tget_task_struct(task);\n}\nrcu_read_unlock();\n\nThe effect on the rest of the kernel is that put_task_struct becomes cheaper\nand immediate, and in the case where the task has been reaped it frees the\ntask immediate instead of unnecessarily waiting an until the rcu interval is\nover.\n\nCleanup of task_struct does not happen when its reference count drops to\nzero, instead cleanup happens when release_task is called. Tasks can only\nbe looked up via rcu before release_task is called. All rcu protected\nmembers of task_struct are freed by release_task.\n\nTherefore we can move call_rcu from put_task_struct into release_task. And\nwe can modify release_task to not immediately release the reference count\nbut instead have it call put_task_struct from the function it gives to\ncall_rcu.\n\nThe end result:\n\n- get_task_struct is safe in an rcu context where we have just looked\n up the task.\n\n- put_task_struct() simplifies into its old pre rcu self.\n\nThis reorganization also makes put_task_struct uncallable from modules as\nit is not exported but it does not appear to be called from any modules so\nthis should not be an issue, and is trivially fixed.\n\nSigned-off-by: Eric W.
