|
|
<para>This VFS module is part of the
|
|
<citerefentry><refentrytitle>samba</refentrytitle>
|
|
<manvolnum>7</manvolnum></citerefentry> suite.</para>
|
|
|
|
<para>The <command>aio_pthread</command> VFS module enables asynchronous
|
|
opens (for new files) with <smbconfoption name="aio_pthread:aio open">yes</smbconfoption>
|
|
on platforms which have the pthreads API available,
|
|
support the openat() syscall and support per thread credentials (modern Linux kernels).
|
|
</para>
|
|
|
|
<para>The module makes use of the global thread pool which uses the
|
|
<smbconfoption name="aio max threads"/> option.</para>
|
|
|
|
<para>This module MUST be listed last in any module stack as
|
|
the Samba VFS open interface is not thread-safe. This
|
|
module makes direct openat() system calls and does
|
|
NOT call the Samba VFS open interfaces.</para>

<para>The original Samba software and related utilities
|
|
were created by Andrew Tridgell. Samba is now developed
|
|
by the Samba Team as an Open Source project similar
|
|
to the way the Linux kernel is developed.</para>
