Hi, I'm writing a fuse fs, and need a method to do a lookup of a direntry. I want to know lmdb is an option here. (much reads, not a lot of writes).

A lookup of a dentry is using the parent inode id and the name of the dentry. So you can create the key like:

key = (parentino padded left with zeros to 8 positions) | dentry->name (note: a custom locking method is required to not lock the whole db)

Now does anybod know this is a good method or are there better methods available?
