Hi all,
I noticed CONFIG_BASE_SMALL in different parts
of the kernel code, with ifdef/ifndef.
I wonder what does CONFIG_BASE_SMALL mean?
And how can I configure it, e.g. through make menuconfig?
thanks,

in mbcache? In mbcache.h, MB_CACHE_INDEXES_COUNT is

driver used by disk hosting root filesystem?
Do any commands can work?
thanks,

Hi all,
I have one question about oom killer:
If many processes dealing with network communications,
but due to bad network traffic, the processes have to wait
for a very long time. And meanwhile they may consume
some memeory separately for computation. The number
of such processes may be
