* cluster/afr: Move deleted files to /.trash in entry self-heal.Vikas Gorur2009-10-294-33/+226
| | | | | | | | | | | | | | | | | If entry self-heal determines that a file/directory should be deleted from a subvolume, move that entry to a directory called "/.trash" on that subvolume. This is for two reasons: 1) It limits the damage that can be done by a "wrong" entry self-heal. 2) It solves the problem of a to-be-deleted directory not being empty. Signed-off-by: Anand V.

* performance/io-cache: change the hash function used for rbtree based hash table.Raghavendra G2009-10-294-12/+32
| | | | | | | | | | | | | | | - the earlier hash function does not distribute pages uniformly for offsets that fit into 32 bits. The reason is that the hash function just xors the contents of the key 4 bytes at a time with the current value of hash. Hence for keys that fit into 32 bits, the hash will be the key itself. Since we are using the rounded_offset (which is a multiple of 128KB) as the key, the key will be exactly divisible by the number of buckets configured (4096) resolving all the pages into the first bucket.
