I would suggest this straightforward solution to this:

a) define a EVENTFS_MAX_INODES (e.g. 4096 * 8),

b) keep track of inode allocation in a bitmap (within a single page),

c) disallow allocating more than "EVENTFS_MAX_INODES" in eventfs.

... reinventing the IDA?

Looking at include/linux/idr.h now that you mention it, yes,
you are absolutely right!

Thanks,

Mathieu
