[PATCH] vfs/eCryptfs: Handle ioctl calls with unlocked and compat functions
Lower filesystems that only implement unlocked_ioctl aren't being passed ioctl calls because eCryptfs only checked for lower_file->f_op->ioctl and returned -ENOTTY if it was NULL. eCryptfs shouldn't implement ioctl(), since it doesn't require the BKL. Instead, unlocked_ioctl() should be used and vfs_ioctl() can b... 20 May 2010 20:30
