Download: http://ftp.intron.ac/tmp/linux_aio-20060922.tar.bz2 Updated files: linux_aio.c vfs_aio.c.diff readme.txt 1. Flexible on-demand linking to FreeBSD native AIO module. Only when linux_io_xxx() is called will native AIO module be loaded. 2. Only two symbols "aio_init_aioinfo" and "aio_aqueue" of the native AIO module need to be exported. Alexander, please roll back "vfs_aio.c", and then apply my new patch "vfs_aio.c.diff", to conform to POLA (Principle Of Least Astonishment). And please change the value of "EXPORT_SYMS" in "/sys/modules/aio/Makefile". ------------------------------------------------------------------------ From Beijing, China Alexander Leidinger wrote: > > Wait... the aio stuff you need is already made global (instead of > static) and exported by the module.
