o What guidelines should I follow when writing code that uses RCU? diff -git a/Documentation/RCU/torture.txt b/Documentation/RCU/torture.txt + "srcu_read_lock", "srcu_read_unlock", "synchronize_rcu", + "synchronize_net", and "synchronize_srcu". diff -git a/Documentation/RCU/rcu.txt b/Documentation/RCU/rcu.txt + + Note that, rcu_assign_pointer() and rcu_dereference() relate to + SRCU just as they do to other forms of RCU.
+ Therefore, SRCU should be used in preference to rw_semaphore + only in extremely read-intensive situations, or in situations + requiring SRCU's read-side deadlock immunity or low read-side + realtime latency. + Second, grace-period-detection overhead is amortized only + over those updates sharing a given srcu_struct, rather than + being globally amortized as they are for other forms of RCU. + + The ability to sleep in read-side critical sections does not + come for free.ğirst, corresponding srcu_read_lock() and + srcu_read_unlock() calls must be passed the same srcu_struct. + Therefore, SRCU is less prone to OOM the system than RCU would + be if RCU's read-side critical sections were permitted to + sleep. This property is what makes sleeping read-side + critical sections tolerable - a given subsystem delays only + its own updates, not those of other subsystems using SRCU. A given synchronize_srcu() waits only + for SRCU read-side critical sections governed by srcu_read_lock() + and srcu_read_unlock() calls that have been passd the same + srcu_struct. Once initialized, + the srcu_struct is passed to srcu_read_lock(), srcu_read_unlock() + and synchronize_srcu(). These are passed a "struct srcu_struct" + that defines the scope of a given SRCU domain. + +Ělso unlike other forms of RCU, explicit initialization + and cleanup is required via init_srcu_struct() and + cleanup_srcu_struct(). Please note that if you + don't need to sleep in read-side critical sections, you should + be using RCU rather than SRCU, because RCU is almost always + faster and easier to use than is SRCU. Unlike other forms of + RCU, it -is- permissible to block in an SRCU read-side critical + section (demarked by srcu_read_lock() and srcu_read_unlock()), + hence the "SRCU": "sleepable RCU". SRCU (srcu_read_lock(), srcu_read_unlock(), and synchronize_srcu()) + may only be invoked from process context. +++ -221,3 +221,41 irq on a given acquisition of that lock will result in deadlock as soon as the RCU callback happens to interrupt that acquisition's critical section. +++ -158,6 +158,7 !Emm/memory.c !Emm/vmalloc.c +!Imm/page_alloc.c !Emm/mempool.c !Emm/page-writeback.c !Emm/truncate.c diff -git a/Documentation/DocBook/libata.tmpl b/Documentation/DocBook/libata.tmpl a/Documentation/DocBook/kernel-api.tmpl 3293,6 +3303,12 MacGregor A.C.T 2615 S: Australia +N: Josh Triplett +E: +P: 1024D/D0FE7AFB B24A 65C9 1D71 2AC2 DE87 CA26 189B 9946 D0FE 7AFB +D: rcutorture maintainer +D: lock annotations, finding and fixing lock bugs + N: Winfried Trümper E: W: diff -git a/Documentation/DocBook/kernel-api.tmpl b/Documentation/DocBook/kernel-api.tmpl
