[Linux-NTFS-cvs] CVS: ntfsprogs/libntfs dir.c,1.57,1.58

[Yura P. <yu...@de...>]

Changes by: yura

Update of /cvs/linux-ntfs/ntfsprogs/libntfs
In directory delta357.server4you.de:/tmp/cvs-serv13022/libntfs

Modified Files:
	dir.c 
Log Message:
ntfs_link(): prevent creating of recursive directary structure.

FUSE incorrectly handles case insensitive filesystems: when I try to rename
"/Dir" to "/DIR", ntfsmount receive rename("/Dir", "/DIR/Dir") call.
This patch do not fix rename, but prevent fs corruption. I will mail Miklos
about this problem.
