nginx: src/os/unix/ngx_files.c annotate

annotate src/os/unix/ngx_files.c @ 6298:8f6d753c1953

Adjusted file->sys_offset after the write() syscall. This fixes suboptimal behavior caused by surplus lseek() for sequential writes on systems without pwrite(). A consecutive read after write might result in an error on systems without pread() and pwrite(). Fortunately, at the moment there are no widely used systems without these syscalls.
