.SH "NAME"
|
|
vfs_aio_pthread \- implement async open in Samba vfs using a pthread pool
|
|
.SH "SYNOPSIS"
|
|
.HP \w'\ 'u
|
|
vfs objects = aio_pthread
|
|
.SH "DESCRIPTION"
|
|
.PP
|
|
This VFS module is part of the
|
|
\fBsamba\fR(7)
|
|
suite\&.
|
|
.PP
|
|
The
|
|
aio_pthread
|
|
VFS module enables asynchronous opens (for new files) with
|
|
\m[blue]\fBaio_pthread:aio open = yes\fR\m[]
|
|
on platforms which have the pthreads API available, support the openat() syscall and support per thread credentials (modern Linux kernels)\&.
|
|
.PP
|
|
The module makes use of the global thread pool which uses the
|
|
\m[blue]\fBaio max threads\fR\m[]
|
|
option\&.
|
|
.PP
|
|
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\&.
|
|
.SH "EXAMPLES"
|
|
.PP
|
|
Straight forward use:
|
|
.sp
|
|
.if n \{\

|
.RS 4
|
|
.\}
|
|
.nf
|
|
\fI[cooldata]\fR

\m[blue]\fBvfs objects = aio_pthread\fR\m[]
|

\m[blue]\fBaio_pthread:aio open = yes\fR\m[]

.SH "OPTIONS"

aio_pthread:aio open = BOOL

.SH "AUTHOR"

|
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\&.
