eCryptfs: Fix new inode race condition
Only unlock and d_add() new inodes after the plaintext inode size has been read from the lower filesystem. This fixes a race condition that was sometimes seen during a multi-job kernel build in an eCryptfs mount. https://bugzilla.kernel.org/show_bug.cgi?id=36002 Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com> Reported-by: David <david@unsolicited.net> Tested-by: David <david@unsolicited.net>
