annotate src/os/unix/ngx_aio_read.c @ 4403:c8b9f62cb414

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fixed sched_setaffinity(2) to correctly pass size. Second argument (cpusetsize) is size in bytes, not in bits. Previously used constant 32 resulted in reading of uninitialized memory and caused EINVAL to be returned on some Linux kernels.
