829f0bcb - vfs: add the concept of vnode state transitions

Mon, 19 Dec 2022 13:00:30 +0000

vfs: add the concept of vnode state transitionsTo quote from a comment above vput_final:* XXX Some filesystems pass in an exclusively locked vnode and strongly depend* on the lock being held all the way until VOP_INACTIVE. This in particular* happens with UFS which adds half-constructed vnodes to the hash, where they* can be found by other code.As is there is no mechanism which allows filesystems to denote that avnode is fully initialized, consequently problems like the above areonly found the hard way(tm).Add rudimentary support for state transitions, which in particular allowto assert the vnode is not legally unlocked until its fate is decided(either construction finishes or vgone is called to abort it).The new field lands in a 1-byte hole, thus it does not grow the struct.Bump __FreeBSD_version to 1400077Reviewed by: kib (previous version)Tested by: phoDifferential Revision: https://reviews.freebsd.org/D37759 List of files: /freebsd-14.2/sys/fs/ext2fs/ext2_alloc.c

Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that arestill not MPSAFE (or already are but aren’t properly marked).Use it in preparation for a general review of all nodes.This is non-functional change that adds annotations to SYSCTL_NODE andSYSCTL_PROC nodes using one of the soon-to-be-required flags.Mark all obvious cases as MPSAFE.
