I was going through the functions like generic_file_write, generic_file_direct_IO, generic_direct_IO and filemap_fdatasync. I was thinking about calling these functions or calling functions written on similar lines to add new few bytes to the file when the inode is created by "ext2_create()". Can any1 please tell me how to do this?
I guess it would have been simpler to call these functions in the call sys_open() when a new file is created, but I want to make changes in kernel code only in ext2 module. playing with sys_open will be like modifying kernel code apart from the ext2 fs module which I dont want.
Thanks and regards,
Vineet
