Dentry cache hash table entries: (order: 6, bytes) Inodecache hash table entries: (order: 5, bytes) Memory: 499MB 499MB total. Dquotcache hash table entries: 1024 (order 0, 4096 bytes) fuse init (API version 7. 22) msgmni has been set to 972.Dentry objects are stored in a slab allocator cache called dentrycache; dentry objects are thus created and destroyed by invoking kmemcachealloc( ) and kmemcachefree( ). Table 125. The fields of the dentry object; d hash. Pointers for list in hash table entry. struct list head. d dentry cache hash table

A set of dentry objects in the inuse, unused, or negative state. A hash table to derive the dentry object associated with a given filename and a given directory quickly. As usual, if the required object is not included in the dentry cache, the hashing function returns a null value.

The hash table is implemented by means of a dentryhashtable array. Each element is a pointer to a list of dentries that hash to the same hash table value. The array's size usually depends on the amount of RAM installed in the system; the default value is 256 entries per megabyte of RAM. Hi Linus, Andrew, Here's a patch to allocate memory for big system hash tables with the bootmem allocator rather than with main page allocator. I've coelesced the meat of the inode and dentry allocation routines into one such routine in mmpagealloc. c that the the respective initialisation functions now call before meminit() is called. dentry cache hash table PID hash table entries allocated as 2N struct hlistheads, which on a 64bit system are 8 bytes each. 2128. . InodeDentry caches are allocated as 2N pages, usually 4096 bytes each. .
