I am trying to understand which processes are accessing files in my filysystem and which files are accessed.
I added a print each time the SD card is being accessed, but I can figure out who's accessing and what, as the final access is done by the 'kworker' process, so using stack-calls won't help.
I noticed that in the first 60~75 seconds after boot, at least 2 access are done both to EXT partitions (i.e rootfs) and to FAT(i.e boot) partitions (I know that at least one of them is to the superblock , as I can know the block id).
How can I find which files are accessed and by which process/app? I want to minimize the SD accesses, without making these partitions READ ONLY.
