[Linux-NTFS-cvs] CVS: ntfsprogs/include/ntfs support.h,1.14,1.15

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

Changes by: yura

Update of /cvs/linux-ntfs/ntfsprogs/include/ntfs
In directory delta357:/tmp/cvs-serv26130/include/ntfs

Modified Files:
	support.h 
Log Message:
Spent really a lot of time applying various "optimizations" from ntfs-3g and
finally figured out that ntfs-3g is faster than ntfsmount only because of
3 reasons:
1) turned on noatime option by default
2) ntfs-3g builds without debug output by default
3) the only real optimization: almost always add resident attributes.
However by accident patch in ntfs-3g for 3) breaks several code paths (why
I am not surprised?), thus I rewrote whole ntfs_attr_add() logic.
