performance/md-cache: purge cache on ENOENT/ESTALE errors

2018-04-25T07:01:17+00:00

If not, next lookup could be served from cache and can be success,
which is wrong. This can affect retry logic of VFS when it receives an
ESTALE.

md-cache: Implement dynamic configuration of xattr list for caching

2018-01-22T04:10:52+00:00

Currently, the list of xattrs that md-cache can cache is hard coded
in the md-cache.c file, this necessiates code change and rebuild
everytime a new xattr needs to be added to md-cache xattr cache
list.

With this patch, the user will be able to configure a comma
seperated list of xattrs to be cached by md-cache

Updates #297

all: Simplify component message id's definition

2017-12-14T02:33:51+00:00

This patch creates a new way of defining message id's that is easier
and less error prone because it doesn't require so many manual changes
each time a new component is defined or a new message created.
