dcache: remove unnecessary NULL check in dget_dlock() (2023-11-25 02:51:56 -0500)
Two conflicts - one is the usual append vs. append in D/f/porting.rst; a slightly
more interesting one in fs/tracefs/inode.c, where the switch of d_child/d_subdirs
to hlist runs into changes made in mainline by "eventfs: Fix file and directory
uid and gid ownership". Pretty straightforward; I've pushed my resolution variant
into #resolution-candidate. Note that subsequent changes in tracefs tree eliminate
the entire "walk the tree and flip ->i_gid" thing, so the entire clone of d_walk()
in set_gid() will be gone anyway...
----------------------------------------------------------------
dcache stuff for this cycle
change of locking rules for __dentry_kill(), regularized refcounting
rules in that area, assorted cleanups and removal of weird corner
cases (e.g. now ->d_iput() on child is always called before the parent
might hit __dentry_kill(), etc.)

----------------------------------------------------------------
Al Viro (41):
struct dentry: get rid of randomize_layout idiocy
get rid of __dget()
DCACHE_... ->d_flags bits: switch to BIT()
DCACHE_COOKIE: RIP
kill d_{is,set}_fallthru()
dentry.h: trim externs
[software coproarchaeology] dentry.h: kill a mysterious comment
kill d_backing_dentry()
Merge branch 'no-rebase-overlayfs' into work.dcache-misc
switch nfsd_client_rmdir() to use of simple_recursive_removal()
coda_flag_children(): cope with dentries turning negative
dentry: switch the lists of children to hlist
centralize killing dentry from shrink list
shrink_dentry_list(): no need to check that dentry refcount is marked dead
fast_dput(): having ->d_delete() is not reason to delay refcount decrement
fast_dput(): handle underflows gracefully
fast_dput(): new rules for refcount
__dput_to_list(): do decrement of refcount in the callers
make retain_dentry() neutral with respect to refcounting
__dentry_kill(): get consistent rules for victim's refcount
dentry_kill(): don't bother with retain_dentry() on slow path
Call retain_dentry() with refcount 0
fold the call of retain_dentry() into fast_dput()
don't try to cut corners in shrink_lock_dentry()
fold dentry_kill() into dput()
to_shrink_list(): call only if refcount is 0
switch select_collect{,2}() to use of to_shrink_list()
d_prune_aliases(): use a shrink list
__dentry_kill(): new locking scheme
retain_dentry(): introduce a trimmed-down lockless variant
kill d_instantate_anon(), fold __d_instantiate_anon() into remaining caller
d_alloc_pseudo(): move setting ->d_op there from the (sole) caller
nsfs: use d_make_root()
Merge branch 'merged-selinux' into work.dcache-misc
simple_fill_super(): don't bother with d_genocide() on failure
d_genocide(): move the extern into fs/internal.h
get rid of DCACHE_GENOCIDE
d_alloc_parallel(): in-lookup hash insertion doesn't need an RCU variant
__d_unalias() doesn't use inode argument
Merge branches 'work.dcache-misc' and 'work.dcache2' into work.dcache
kill DCACHE_MAY_FREE
Amir Goldstein (1):
ovl: stop using d_alloc_anon()/d_instantiate_anon()
