The cost of devfs is a small increase in kernel code size and memory
usage. About 7 pages of code (some of that in __init sections) and 72
bytes for each entry in the namespace. A modest system has only a
couple of hundred device entries, so this costs a few more
pages. Compare this with the suggestion to put /dev on a <a
On a typical machine, the cost is under 0.2 percent. On a modest
system with 64 MBytes of RAM, the cost is under 0.1 percent. The
accusations of "bloatware" levelled at devfs are not justified.
