| |
Dear all,
I am having trouble in reading a file in the kernel space using the file->f_op->read call, everything is ok. I start off file->f_pos = 0 . I also did a mntget to the super block before I call "file=dentry_open(.....)" . I intend to open the file in read only mode. What can be wrong? I have also check the inode->i_size is large enough for me to just read 8 bytes from the file. I keep having EFAULT error from the read call... also before calling mntget, also did a dget to the dentry. Any help is welcomed. Thanks.
regards,
