# commit 6faf05c2b2b4fe70d9068067437649401531de0a
# Author: Miklos Szeredi <miklos@szeredi.hu>
# Date:   Wed Aug 22 10:55:22 2018 +0200
# 
#     ovl: set I_CREATING on inode being created
#     
#     ...otherwise there will be list corruption due to inode_sb_list_add() being
#     called for inode already on the sb list.
#     
#     Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
#     Fixes: e950564b97fd ("vfs: don't evict uninitialized inode")
