Can someone please explain which of these defines controls the maximum
number of open files per process? In include/linux/limits.h, the comment
for OPEN_MAX is /* # open files a process may have */, but I don't see any
code using OPEN_MAX except for arch/sparc/kernel/sys_sunos.c.
NR_OPEN, on the other hand, is used quite a bit, but is uncommented. Plus
it is defined in limits.h, and then undef'ed and redefined in fs.h. Is
the NR_OPEN defined in limits.h redundant, and the true NR_OPEN in fs.h?
