* libglusterfsclient: handle intermediate path components which are symlinks ↵Raghavendra G2009-09-081-5/+10
| | | | | | | | | | | | | properly in glusterfs_glh_realpath. - while building the realpath, if the intermediate path happens to be a symbolic link, the content of link was being appended at dirname (path), instead of appending to intermediate path.

Avati <avati@dev.gluster.com> BUG: 237 (If any of the path component other than the last one, happens to be a symbolic link glusterfs_glh_realpath does not construct correct path.)

* storage/posix: handle dentries from different mount points in readdirRaghavendra G2009-09-081-34/+51
| | | | | | | | | | | | | | | | | - If posix translator is configured to have export directories to span accross different mount points, inode number is transformed in the dentry returned. Otherwise, the entry is not added to list of entries returned in readdir callback. - storage/posix returns ENOENT if the file is on different mount point other than that of exported directory and is not configured for export directory spanning across multiple mountpoints during lookup. But, since stat-prefetch shortcuts lookup calls, its necessary that readdir return only valid dentries. Signed-off-by: Anand V.
