features/locks: implement fgetxattr and fsetxattr

2012-11-28T06:54:27+00:00

implement xattrs for GF_XATTR_LOCKINFO_KEY, which will be used
for posix-locks migration from old to new graph after a switch.

fgetxattr (fd, GF_XATTR_LOCKINFO_KEY) will return a dict.
This dict has a serialized dict stored for key
GF_XATTR_LOCKINFO_KEY. This serialized dict in turn has fdnum
value of locks acquired on this fd with modified pathinfo
(containing hostname and base directory components) as key.

fsetxattr (newfd, GF_XATTR_LOCKINFO_KEY, dict) has following
semantics. dict can be the result of a previous fgetxattr with
GF_XATTR_LOCKINFO_KEY. In that case, a dict_get on dict
constructed using serialized buffer is done on modified pathinfo
as key. If a value is got, that value is treated as fdnum and for
every lock l on newfd->inode we do,
      if (l->fdnum == fdnum) {
         l->fdnum = fd_fdnum (newfd);
         l->transport = ;
      }

core: adding extra data for fops

2012-03-22T23:40:27+00:00

with this change, the xlator APIs will have a dictionary as extra
argument, which is passed between all the layers. This can be
utilized for overloading in some of the operations.

core: utilize mempool for frame->local allocations

2012-02-21T10:42:09+00:00

in each translator, which uses 'frame->local', we are using
GF_CALLOC/GF_FREE, which would be costly considering the
number of allocation happening in a lifetime of 'fop'. It
would be good to utilize the mem pool framework for xlator's
local structures, so there is no allocation overhead.

2012-01-25T04:14:17+00:00

so, NLM can send the lk-owner field directly to the locks translators,
while doing the same effort, also enabled sending maximum of 500 aux gid
over protocol.
