From: Matthew Wilcox Now that the IDR can be used to store large IDs, it is possible somebody might only partially convert their old code and use the iterators which can only handle IDs up to INT_MAX. It's probably unwise to show them a truncated ID, so settle for

[PATCH 03/17] idr test suite: Fix ida_test_random()

From: Matthew Wilcox The test was checking the wrong errno; ida_get_new_above() returns EAGAIN, not ENOMEM on memory allocation failure. Double the number of threads to increase the chance that we actually exercise this path during the test suite (it was a bit sporadic

[PATCH 04/17] IDR test suite: Check handling negative end correctly

From: Matthew Wilcox One of the charming quirks of the idr_alloc() interface is that you can pass a negative end and it will be interpreted as "maximum". Ensure we don't break that. Signed-off-by: Matthew Wilcox ---

[PATCH 05/17] idr: Delete idr_remove_ext function

From: Matthew Wilcox Simply changing idr_remove's 'id' argument to 'unsigned long' suffices for all callers. Signed-off-by: Matthew Wilcox --- include/linux/idr.h| 7 +-- net/sched/act_api.c| 2 +- net/sched/cls_basic.c | 6 +++---

[PATCH 14/17] cls_u32: Convert to idr_alloc_u32

From: Matthew Wilcox No real benefit to this classifier, but since we're allocating a u32 anyway, we should use this function. Signed-off-by: Matthew Wilcox --- net/sched/cls_u32.c | 7 +++ 1 file changed, 3 insertions(+), 4 deletions(-)

[PATCH 13/17] cls_u32: Reinstate cyclic allocation

From: Matthew Wilcox Commit e7614370d6f0 ("net_sched: use idr to allocate u32 filter handles) converted htid allocation to use the IDR. The ID allocated by this scheme changes; it used to be cyclic, but now always allocates the lowest available. The IDR supports cyclic

[PATCH 08/17] idr: Add idr_alloc_u32 helper

From: Matthew Wilcox All current users of idr_alloc_ext() actually want to allocate a u32 and it's a little painful for them to use idr_alloc_ext(). This convenience function makes it simple. Signed-off-by: Matthew Wilcox ---

[PATCH 00/17] IDR patches for 4.15

From: Matthew Wilcox The patches here are of three types: - Enhancing the test suite (fixing the build, adding a couple of new tests, fixing a bug in the test) - Replacing the 'extended' IDR API - Fixing some low-probability bugs As far as the 'extended' IDR API

[PATCH 09/17] net sched actions: Convert to use idr_alloc_u32

From: Matthew Wilcox Use the new helper. Also untangle the error path, and in so doing noticed that estimator generator failure would lead to us leaking an ID. Fix that bug. Signed-off-by: Matthew Wilcox --- net/sched/act_api.c | 60

[PATCH 10/17] cls_basic: Convert to use idr_alloc_u32

[PATCH 06/17] idr: Delete idr_replace_ext function

From: Matthew Wilcox Changing idr_replace's 'id' argument to 'unsigned long' works for all callers. Callers which passed a negative ID now get -ENOENT instead of -EINVAL. No callers relied on this error value. Signed-off-by: Matthew Wilcox ---

[PATCH 15/17] idr: Rename idr_alloc_ext to idr_alloc_ul

From: Matthew Wilcox idr_alloc_ul fits better with other parts of the Linux kernel where we need to name a function based on the types it operates on. It uses a 'nextid' pointer argument instead of separate minimum ID and output assigned ID, (like idr_get_next), reducing

[PATCH net-next] vmxnet3: increase default rx ring sizes

We often notice rx packet drops due to small default rx ring sizes and solve the problem by increasing the ring sizes. This patch increases the default rx ring sizes thereby reducing the probability of rx packet drops out of the box. Signed-off-by: Shrikrishna Khare Acked-by:
