.SH "DESCRIPTION"
.PP
Limit directory size to the page cache limit on architectures where unsigned
long is 32-bits. This is the most we can do for now without overflowing the
page cache page index. Doing it this way means we don't run into problems
because of existing too large directories. It would be better to allow the
user to read the accessible part of the directory but I doubt very much
anyone is going to hit this check on a 32-bit architecture, so there is no
point in adding the extra complexity required to support this.
.PP
On 64-bit architectures, the check is hopefully optimized away by the
compiler.
