In ext2, there is a mechanism for reserving a certain number of blocks
for a particular user (normally the super-user). This is intended to
-allow for the system to continue functioning even if non-priveleged users
+allow for the system to continue functioning even if non-privileged users
fill up all the space available to them (this is independent of filesystem
quotas). It also keeps the filesystem from filling up entirely which
helps combat fragmentation.
so 8kB blocks are only allowed on Alpha systems (and other architectures
which support larger pages).
-There is an upper limit of 32768 subdirectories in a single directory.
+There is an upper limit of 32000 subdirectories in a single directory.
There is a "soft" upper limit of about 10-15k files in a single directory
with the current linear linked-list directory implementation. This limit
