I am trying to trace the function class involved with a file read through
the ext2 file system. I figured that the disk driver access point is
ll_rw_block in linux/drivers/block/ll_rw_blk.c. There are 3 places this
function is called as far as the read is concerned.
1. block_read in linux/fs/block_dev.c
2. brw_page in linux/fs/buffer.c
3. bread in linux/fs/buffer.c
Can some one please tell me what function is used by ext2 file system ?
If you can give me information as to how I could track this down inside
the kernel and file system I will be very grateful.
Some help is much appreciated
Thank you
Ravi
