bfs_file_rename() and remove the bfs_file_delete() from bfs_file_rename().
After calling bfs_file_rename() it was too late to set "tnode->removed"
as the inode already disappeared.
find.
The filesystem ones all call genfs_eopnotsupp - right now I am only
implementing the plumbing and we can implement fallocate and/or
fdiscard for files later.
The device ones call spec_fallocate (which is also genfs_eopnotsupp)
and spec_fdiscard, which dispatches to the device-level op.
The fifo ones all call vn_fifo_bypass, which also ends up being
EOPNOTSUPP.
Defer the destruction to sysvbfs_reclaim().
Disable test t_renamerace:sysvbfs_renamerace as it will exhaust the
inode table (sysvbfs has space for 8 inodes only).
Ok: Izumi Tsutsui <tsutsui@netbsd.org>
A type specifier of the form
enum identifier
without an enumerator list shall only appear after the type it
specifies is complete.
which means that we cannot pass an "enum vtype" argument to
kauth_access_action() without fully specifying the type first.
Unfortunately there is a complicated include file loop which
makes that difficult, so convert this minimal function into a
macro (and capitalize it).
(ok elad@)
(and rename it to sysvbfs_file_setsize()) because it's actually
part of vnode ops and bfs.c is also pulled by standalone bootloaders
which don't want vnode header mess.
translate FSYNC_LAZY into PGO_LAZY for VOP_PUTPAGES() so that
genfs_do_io() can set the appropriate io priority for the I/O.
this is the first part of addressing PR 46325.
- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.
- Simplify locking in some pmap(9) modules by removing P->V locking.
- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).
- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.
- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.
Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.
pathbuf object passed to namei as work space instead. (For now a pnbuf
pointer appears in struct nameidata, to support certain unclean things
that haven't been fixed yet, but it will be going away in the future.)
This removes the need for the SAVENAME and HASBUF namei flags.
to do two things:
1) properly set "recycle?" in inactive
2) easily check if we are renaming a removed vnode. without the
check, it was possible to enter a dirent in the file system for
a removed (and hence scheduled to be vcleaned) vnode. this would
lead to the succesful vget() of a clean vnode. the use of the
cleaned vnode was, however, less succesful, except for purposes
of crashing.
the value before the call (yea, changing relookup would probably
be smart, but other file systems already initialize vpp, so I'm
letting someone else experiment with tylenol od).
years ago when the kernel was modified to not alter ABI based on
DIAGNOSTIC, and now just call the respective function interfaces
(in lowercase). Plenty of mix'n match upper/lowercase has creeped
into the tree since then. Nuke the macros and convert all callsites
to lowercase.
