The patch titled
Move LOG_BUF_SHIFT to a more sensible place
has been removed from the -mm tree. Its filename was
move-log_buf_shift-to-a-more-sensible-place.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Move LOG_BUF_SHIFT to a more sensible place
From: Alistair John Strachan <s0348365@xxxxxxxxxxxx>
Several people have observed that perhaps LOG_BUF_SHIFT should be in a more
obvious place than under DEBUG_KERNEL. Under some circumstances (such as the
PARISC architecture), DEBUG_KERNEL can increase kernel size, which is an
undesirable trade off for something as trivial as increasing the kernel log
buffer size.
Instead, move LOG_BUF_SHIFT into "General Setup", so that people are more
likely to be able to change it such a circumstance that the default buffer
size is insufficient.
