Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

sunrpc: use the struct net as the svc proc private

2024-03-01T14:12:09+00:00

nfsd is the only thing using this helper, and it doesn't use the private currently. When we switch to per-network namespace stats we will need the struct net * in order to get to the nfsd_net. Use the net as the proc private so we can utilize this when we make the switch over. Signed-off-by: Josef Bacik Reviewed-by: Jeff Layton Signed-off-by: Chuck Lever

proc: convert everything to "struct proc_ops"

SUNRPC: Count ops completing with tk_status < 0

2019-07-06T18:54:51+00:00

We often see various error conditions with NFS4.x that show up with a very high operation count all completing with tk_status < 0 in a short period of time. Add a count to rpc_iostats to record on a per-op basis the ops that complete in this manner, which will enable lower overhead diagnostics.

SUNRPC: enhance rpc_clnt_show_stats() to report on all xprts.

2019-07-06T18:54:51+00:00

Now that a client can have multiple xprts, we need to report the statistics for all of them. Reported-by: Chuck Lever Signed-off-by: NeilBrown Signed-off-by: Trond Myklebust

SUNRPC: Use proper printk specifiers for unsigned long long
