2009-09-15Staging: echo: top bit patchDavid Rowe
This patch removes the need for the bit_operations.h include file which can now be deleted. It also contains some minor corrections to comments (typos and alignment of ASCII formulas). I have also removed some #if lines that were not necessary. I have tested the patch using a unit test module that runs in kernel mode and have verified that the patched code gives identical results to the previous version using a 8000 sample input sequence. Let me know if you want this unit test, it runs automatically when the module is insmod-ed and outputs a go/no go result: # insmod oslec.ko # dmesg [17191803.480000] oslec_test installed [17191803.480000] Testing OSLEC with 128 taps (16 ms tail) [17191803.496000] Oslec Unit Test PASSED! pass: 8000 fail: 0 Signed-off-by: David Rowe <david@rowetel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-06-19Staging: oslec bug fixDavid Rowe
I have just had a bug fix submitted for Oslec which I have applied to Oslec SVN. The bug can potentially stops the echo canceller adapting after a few seconds, although it hasn't caused many problems in practice.
