[patch 08/15] fat: dont call notify_change

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Miklos Szeredi <mszeredi@xxxxxxx>

The FAT_IOCTL_SET_ATTRIBUTES ioctl() calls notify_change() to change
the file mode before changing the inode attributes.  Replace with
explicit call to fat_setattr().

This is equivalent, except that security_inode_setattr() is not called
before fat_setattr().  I think this is not needed, since the mode
change is just a side effect of the attribute change.
