[ Upstream commit2c63986dd3] When creating and destroying inodes, we are relying on the inode hash table to make sure that for a given inode number, only a single inode will exist. We then link that inode to its inode and iopen glock and let those glocks point back at the inode. However, when iget_failed() is called, the inode is removed from the inode hash table before gfs_evict_inode() is called, and uniqueness is no longer guaranteed. Commit f1046a472b70 ("gfs2: gl_object races fix") was trying to work around that problem by detaching the inode glock from the inode before calling iget_failed(), but that broke the inode deallocation code in gfs_evict_inode(). To fix that, deallocate partially created inodes in gfs2_create_inode() instead of relying on gfs_evict_inode() for doing that. This means that gfs2_evict_inode() and its helper functions will no longer see partially created inodes, and so some simplifications are possible there.
