9p: Use a slab for allocating requests

2018-08-29T04:39:57Z

Replace the custom batch allocation with a slab. Use an IDR to store pointers to the active requests instead of an array. We don't try to handle P9_NOTAG specially; the IDR will happily shrink all the way back once the TVERSION call has completed.

net:mod: remove unneeded variable 'ret' in init_p9

2018-08-08T16:40:44Z

The ret is modified after initalization, so just remove it and return 0. Signed-off-by: zhong jiang Signed-off-by: David S. Miller

net/9p: correct the variable name in v9fs_get_trans_by_name() comment

2018-05-08T03:38:15Z

The v9fs_get_trans_by_name(char *s) variable name is not "name" but "s". Signed-off-by: Sun Lianwen Signed-off-by: David S. Miller

9p: Reduce object size with CONFIG_NET_9P_DEBUG

2012-01-05T16:51:44Z

Reduce object size by deduplicating formats. Use vsprintf extension %pV. Rename P9_DPRINTK uses to p9_debug, align arguments. Add function for _p9_debug and macro to add __func__. Add missing "\n"s to p9_debug uses. Remove embedded function names as p9_debug adds it. Remove P9_EPRINTK macro and convert use to pr_. Add and use pr_fmt and pr_. $ size fs/9p/built-in.o* text data bss dec hex filename 62133 984 16000 79117 1350d fs/9p/built-in.o.new 67342 984 16928 85254 14d06 fs/9p/built-in.o.old $ size net/9p/built-in.o* text data bss dec hex filename 88792 4148 22024 114964 1c114 net/9p/built-in.o.new 94072 4148 23232 121452 1da6c net/9p/built-in.o.old Signed-off-by: Joe Perches Signed-off-by: Eric Van Hensbergen

net/9p: Change linuxdoc names to match functions.

2011-05-25T13:46:37Z

As on Jeopardy, my question is in the form of a patch: Does this have some special meaning, or is it an accident? (I looked at other filesystems but they didn't bother having doc entries for their init/exit function that I could find.) Signed-off-by: Rob Landley Signed-off-by: Eric Van Hensbergen

9p: consolidate transport structure

2008-10-17T16:04:41Z

Right now there is a transport module structure which provides per-transport type functions and data and a transport structure which contains per-instance public data as well as function pointers to instance specific functions. This patch moves public transport visible instance data to the client structure (which in some cases had duplicate data) and consolidates the functions into the transport module structure.

9p: implement proper trans module refcounting and unregistration

2008-09-24T21:22:23Z

9p trans modules aren't refcounted nor were they unregistered properly. Fix it. * Add 9p_trans_module->owner and reference the module on each trans instance creation and put it on destruction. * Protect v9fs_trans_list with a spinlock. This isn't strictly necessary as the list is manipulated only during module loading / unloading but it's a good idea to make the API safe. * Unregister trans modules when the corresponding module is being unloaded. * While at it, kill unnecessary EXPORT_SYMBOL on p9_trans_fd_init().

9p: fix error path during early mount

2008-05-15T00:23:27Z

There was some cleanup issues during early mount which would trigger a kernel bug for certain types of failure. This patch reorganizes the cleanup to get rid of the bad behavior. This also merges the 9pnet and 9pnet_fd modules for the purpose of configuration and initialization. Keeping the fd transport separate from the core 9pnet code seemed like a good idea at the time, but in practice has caused more harm and confusion than good. Signed-off-by: Eric Van Hensbergen

9p: Documentation updates

2008-05-15T00:23:25Z

The kernel-doc comments of much of the 9p system have been in disarray since reorganization. This patch fixes those problems, adds additional documentation and a template book which collects the 9p information. Signed-off-by: Eric Van Hensbergen
