Hi Robert, You have a small typo in the patch:
+ /* + * pagesize will, for practical purposes, always be a power of two. + * But just in case it isn't, we do it this way instead of using + * TYPEALIGN(). + */ + AnonymousShmemSize = size; + if (size % pagesize != 0) + AnonymousShmemSize += pagesize - (size % pagesize); + + /* + * We assume that no one will attempt to run PostgreSQL 9.3 or later + * on systems that are ancient enough that anonymous shared memory is + * not supported, such as pre-2.4 versions of Linux. If that turns out + * to be false, we might need to add a run-time test here and do this + * only if the running kernel supports it. + */ + AnonymousShmem = mmap(NULL, size, PROT_READ|PROT_WRITE, PG_MMAP_FLAGS, + -1, 0); Note that you use size in the mmap...
