Mauricio Lin	e070ad49f3	[PATCH] add /proc/pid/smaps ... Add a "smaps" entry to /proc/pid: show howmuch memory is resident in each mapping. People that want to perform a memory consumption analysing can use it mainly if someone needs to figure out which libraries can be reduced for embedded systems. So the new features are the physical size of shared and clean [or dirty]; private and clean [or dirty]. Take a look the example below: # cat /proc/4576/smaps 08048000-080dc000 r-xp /bin/bash Size: 592 KB Rss: 500 KB Shared_Clean: 500 KB Shared_Dirty: 0 KB Private_Clean: 0 KB Private_Dirty: 0 KB 080dc000-080e2000 rw-p /bin/bash Size: 24 KB Rss: 24 KB Shared_Clean: 0 KB Shared_Dirty: 0 KB Private_Clean: 0 KB Private_Dirty: 24 KB 080e2000-08116000 rw-p Size: 208 KB Rss: 208 KB Shared_Clean: 0 KB Shared_Dirty: 0 KB Private_Clean: 0 KB Private_Dirty: 208 KB b7e2b000-b7e34000 r-xp /lib/tls/libnss_files-2.3.2.so Size: 36 KB Rss: 12 KB Shared_Clean: 12 KB Shared_Dirty: 0 KB Private_Clean: 0 KB Private_Dirty: 0 KB ... (Includes a cleanup from "Richard Purdie" <rpurdie@rpsys.net>) From: Torsten Foertsch <torsten.foertsch@gmx.net> show_smap calls first show_map and then prints its additional information to the seq_file. show_map checks if all it has to print fits into the buffer and if yes marks the current vma as written. While that is correct for show_map it is not for show_smap. Here the vma should be marked as written only after the additional information is also written. The attached patch cures the problem. It moves the functionality of the show_map function to a new function show_map_internal that is called with an additional struct mem_size_stats* argument. Then show_map calls show_map_internal with NULL as struct mem_size_stats* whereas show_smap calls it with a real pointer. Now the final if (m->count < m->size) /* vma is copied successfully */ m->version = (vma != get_gate_vma(task))? vma->vm_start: 0; is done only if the whole entry fits into the buffer.

Cosmin Nicolaescu	c31403a1f5	[PATCH] Documentation: remove super-{nr, max} to reflect fs/super.c ... The patch updates the documentation for /proc. super-nr and super-max have been dropped from the kernel since 2.4.9 due to minor numbering issues. This change was not documented in the documentation.

Linus Torvalds	1da177e4c3	Linux-2.6.12-rc2 ... Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!	2005-04-16 15:20:36 -07:00
