---help---
|
|
This setting controls the number of other modules that a new module
|
|
may depend on. That is, when a new module in inserted via 'insmod'
|
|
it may depend on symbols exported by other, already installed
|
|
modules. This is the maximum number of modules that export symbols
|
|
to the new module. This maximum is artificial; it is used in the
|
|
current design because it uses some very simple, pre-allocated data
|
|
structures.
|
|
|
|
All dependencies logic my be eliminated by sett CONFIG_MODLIB_MAXDEPEND
|

to zero.

This is an I/O buffer that is used to access the module file.

Variable length items will need to be read (such as symbol names).

This is really just this initial size of the buffer; it will be
