Re: File size from Linux Kernel Module

Do a lookup of the file using kern_path kernel function and then use vfs_getattr on file. The kstat->size should be our answer.

Hello All,

I need to do file operations from my driver to upload firmware to another processor DRAM memory. I need to know how to get the file size from the kernel module. 

I am using flip_open, flip_close, vfs_read, vfs_write for file operations. 

Could you please post your comments to my queries?

Thanks,
