Linux doesn't swap any kernel memory. That's a major characteristic of Linux, in comparison to other operating systems. Here, swapping means writing a page to swap space to free up the page frame it was in, and faulting it back in from swap space when someone references the page. >If my understanding is right, inode cache shrinker only frees the >reclaimable inodes, which means, if a lot of files are opened when >shrinker is activated, the shrinker may not find sufficient >reclaimable inodes to free enough space. What will Linux do under such >condition? It will free some other memory instead. If it can't find any, it will terminate processes until it does. If it still can't, the kernel crashes. That's part of why the rlimit on open files is important. -- Bryan Henderson IBM Almaden Research Center San Jose CA Filesystems - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
