| 73 | * this allows allocators to use a synchronize_rcu() to stabilize _count. | ||
| 74 | * | ||
| 75 | * Unless an RCU grace period has passed, the count of all pages coming out | ||

| 79 | * for (because put_page is what is used here to drop an invalid speculative | ||

| 81 | * | ||
| 82 | * This is the interesting part of the lockless pagecache (and lockless | ||
| 83 | * get_user_pages) locking protocol, where the lookup-side (eg. find_get_page) | ||
| 84 | * has the following pattern: | ||
| 85 | * 1. find page in radix tree | ||
| 86 | * 2. conditionally increment refcount | ||
| 87 | * 3. check the page is still in pagecache (if no, goto 1) | ||
| 88 | * | ||
| 89 | * Remove-side that cares about stability of _count (eg. reclaim) has the | ||
| 90 | * following (with tree_lock held for write): | ||
| 91 | * A. atomically check refcount is correct and set it to 0 (atomic_cmpxchg) | ||
| 92 | * B. remove page from pagecache | ||
| 93 | * C. free the page | ||
| 94 | * | ||
| 95 | * There are 2 critical interleavings that matter: | ||
| 96 | * - 2 runs before A: in this case, A sees elevated refcount and bails out | ||
| 97 | * - A runs before 2: in this case, 2 sees zero refcount and retries; | ||
| 98 | * subsequently, B will complete and 1 will find no page, causing the | ||
| 99 | * lookup to return NULL. | ||
| 100 | * | ||
| 101 | * It is possible that between 1 and 2, the page is removed then the exact same | ||
| 102 | * page is inserted into the same position in pagecache. That's OK: the | ||
| 103 | * old find_get_page using tree_lock could equally have run before or after | ||
| 104 | * such a re-insertion, depending on order that locks are granted. | ||
| 105 | * | ||
| 106 | * Lookups racing against pagecache insertion isn't a big problem: either 1 | ||

| 9 | * | ||
| 10 | * This file defines hook entry points called by core code where | ||
| 11 | * user tracing/debugging support might need to do something. These | ||
| 12 | * entry points are called tracehook_*(). Each hook declared below | ||
| 13 | * has a detailed kerneldoc comment giving the context (locking et | ||
| 14 | * al) from which it is called, and the meaning of its return value. | ||
| 15 | * | ||
| 16 | * Each function here typically has only one call site, so it is ok | ||
| 17 | * to have some nontrivial tracehook_*() inlines. In all cases, the | ||
| 18 | * fast path when no tracing is enabled should be very short. | ||
| 19 | * | ||
| 20 | * The purpose of this file and the tracehook_* layer is to consolidate | ||
| 21 | * the interface that the kernel core and arch code uses to enable any | ||
| 22 | * user debugging or tracing facility (such as ptrace). The interfaces | ||
| 23 | * here are carefully documented so that maintainers of core and arch | ||
| 24 | * code do not need to think about the implementation details of the | ||
| 25 | * tracing facilities. Likewise, maintainers of the tracing code do not | ||
| 26 | * need to understand all the calling core or arch code in detail, just | ||
| 27 | * documented circumstances of each call, such as locking conditions. | ||
| 28 | * | ||
| 29 | * If the calling core code changes so that locking is different, then | ||
| 30 | * it is ok to change the interface documented here. The maintainer of | ||
| 31 | * core code changing should notify the maintainers of the tracing code | ||
| 32 | * that they need to work out the change. | ||
| 33 | * | ||
| 34 | * Some tracehook_*() inlines take arguments that the current tracing | ||
| 35 | * implementations might not necessarily use. These function signatures | ||
| 36 | * are chosen to pass in all the information that is on hand in the | ||
| 37 | * caller and might conceivably be relevant to a tracer, so that the | ||
| 38 | * core code won't have to be updated when tracing adds more features. | ||
| 39 | * If a call site changes so that some of those parameters are no longer | ||
| 40 | * already on hand without extra work, then the tracehook_* interface | ||
| 41 | * can change so there is no make-work burden on the core code. The | ||
| 42 | * maintainer of core code changing should notify the maintainers of the | ||
| 43 | * tracing code that they need to work out the change. | ||
