.SH "NAME"
__starget_for_each_device \- helper to walk all devices of a target (UNLOCKED)
.SH "SYNOPSIS"
.HP \w'void\ __starget_for_each_device('u
.BI "void __starget_for_each_device(struct\ scsi_target\ *\ " "starget" ", void\ *\ " "data" ", void\ (*" "fn" ")\ (struct\ scsi_device\ *,\ void\ *));"
.SH "ARGUMENTS"
.PP
\fIstarget\fR
.RS 4
target whose devices we want to iterate over\&.
.RE
.PP
\fIdata\fR
.RS 4
parameter for callback
\fIfn\fR()
.RE
.PP
\fIfn\fR
.RS 4
callback function that is invoked for each device
.RE
.SH "DESCRIPTION"
.PP
This traverses over each device of
\fIstarget\fR\&. It does _not_ take a reference on the scsi_device, so the whole loop must be protected by shost\->host_lock\&.
.SH "NOTE"
.PP
The only reason why drivers would want to use this is because they need to access the device list in irq context\&. Otherwise you really want to use starget_for_each_device instead\&.
