Alexey Gladkov 9220066ea8 docs: add information about ipc sysctls limitations ... After 25b21cb2f6 ("[PATCH] IPC namespace core") and 4e9823111b ("[PATCH] IPC namespace - shm") the shared memory page count stopped being global and started counting per ipc namespace. The documentation and shmget(2) still says that shmall is a global option. shmget(2): SHMALL System-wide limit on the total amount of shared memory, measured in units of the system page size. On Linux, this limit can be read and modified via /proc/sys/kernel/shmall. I think the changes made in 2006 should be documented.
