Re: questions on swapping

Dear Jan Hudec.

Thanks for the information, well i have following difficulties.
1. How to handle/write the Bottom Half part of Interrupt for Device Drivers
2. If any error, then the messages during the running of Device Driver
modules where(in which file) they are written by Kernel, or we have to
specify the location/Pathname of file during the implimentation.

Thanks in advance.

Thanks n Regards
Heerappa.

Buffers are rather transient stuff during IO operations. Kernel will
allocate memory for them as they are needed.

All memory, that is not used by kernel or applications is used for
caching files (page cache). No need to configure that either.
