* Solaris xattr support for symlink and special files.v3.1.3qa3shishir gowda2011-03-041-3/+13
| | | | | | | | | | | | | | | | | | Since glusterfs uses xattr for storing gfid, and xattr support for symlinks and special files does not exist in solaris. The work around is provided by creating hidden files under export directory on solaris hosts only. the hidden files ares maintained in .glusterfs_xattr_inode directory, and all xattr ops on symlink and special files are redirected to respective inodes. All dir entries with name starting as .glusterfs (GF_HIDDEN_PATH) will not be shown in readdir ops. Signed-off-by: shishir gowda <shishirng@gluster.com> Signed-off-by: Anand V.
