wireguard-openbsd/sys/ufs, branch jd/simplify-queueingWireGuard implementation for the OpenBSD kernelhttps://git.zx2c4.com/wireguard-openbsd/atom/sys/ufs?h=jd%2Fsimplify-queueing2020-06-20T07:49:04ZWith filesystem having many cylinder groups and many inodes per cg the2020-06-20T07:49:04Zottootto@openbsd.org2020-06-20T07:49:04Zurn:sha1:abbb35584eeb1f783012251d6de83bc7a1260d24
ncg * ipg calcualtion can overflow if signed types are used. Move
to uint32_t for the relevant values. Aligned with FreeBSD changes.
Also make sure newfs refuses to create an fs with more that 2^32-1
inodes. ok millert@
Rename poll-compatibility flag to better reflect what it is.2020-06-11T09:18:43Zmpimpi@openbsd.org2020-06-11T09:18:43Zurn:sha1:1c57bd6bc2d4b1536ac76e1cdb4ba92124a01e2a
While here prefix kernel-only EV flags with two underbars.

Use a new EV_OLDAPI flag to match the behavior of poll(2) and select(2).2020-06-08T08:04:09Zmpimpi@openbsd.org2020-06-08T08:04:09Zurn:sha1:6e29a9444098b33c28a7ce5b32b593b9539d7294
Adapt FS kqfilters to always return true when the flag is set and bypass
the polling mechanism of the NFS thread.
While here implement a write filter for NFS.

When the preferred cylinder group if full scan forward (wrapping if needed)2020-05-29T06:46:15Zottootto@openbsd.org2020-05-29T06:46:15Zurn:sha1:458c9f6e6301be0ff829aee4a9cbebac06df8f8a
to find another, instead of first forward and then backward. The latter method
causes most full cgs to end up at the end of the partition. From FreeBSD.

Make generation numbers unsigned and fill them using a random number2020-05-28T15:48:28Zottootto@openbsd.org2020-05-28T15:48:28Zurn:sha1:d06c4e1f5435c136423f9e1463cd963b162d217f
from the range [1..UINT_MAX] initially. On inode re-use increment
and on wrap refill from the range [1..UINT_MAX-1] to avoid
assigning UINT_MAX (the original value). Zero still means uninitialized.

Explicitly documents that `vop_kqfilter' isn't missing.2020-05-21T09:35:09Zmpimpi@openbsd.org2020-05-21T09:35:09Zurn:sha1:2061a77758dc497cf61c0ff46c166be2c9693226
Just like most of the vop_* methods in MFS they aren't used.

Abstract the head of knote lists. This allows extending the lists,2020-04-07T13:27:50Zvisavisa@openbsd.org2020-04-07T13:27:50Zurn:sha1:9c969c9ab4dbfc69101f439c13329bb852e9fe18

Avoid a tight CPU loop when no unlocked worklist items can be processed.2020-03-09T16:49:12Zmillertmillert@openbsd.org2020-03-09T16:49:12Zurn:sha1:e2086e682725f53d68e22e4ef655dc2a593916da
If process_worklist_item() is unable to process locked vnodes,
num_on_worklist will still be non-zero, preventing the loop in
softdep_process_worklist() from exiting. This can result in a
kernel hang.
To fix this, process_worklist_item() now returns non-zero if it was
able to process a worklist item (regardless of whether it matched
the mountpoint) and takes a pointer to matchcnt as a function
argument. We now break out of the loop in softdep_process_worklist()
if process_worklist_item() is unable to make progress.

Remove unused "struct proc *" argument from the following functions:2020-02-27T09:10:31Zmpimpi@openbsd.org2020-02-27T09:10:31Zurn:sha1:db7aa9821c9615b2b21dc263b8e1f99309ff4e4a

- ufs_reclaim()
- ext2fs_chown() & ext2fs_chmod()
- ntfs_ntget() & ntfs_ntput()
- ntfs_vgetex(), ntfs_ntlookup() & ntfs_ntlookupfile()
While here use `ap->a_p' directly when it is only required to re-enter
the VFS layer in order to help reducing the loop.
