This postpones the writeout to ocfs2_evict_inode(), which I'm told is fine (tm). The intent is to retire the I_WILL_FREE flag. Signed-off-by: Mateusz Guzik <mjguzik@xxxxxxxxx> --- ACHTUNG: only compile-time tested. Need an ocfs2 person to ack it. btw grep shows comments referencing ocfs2_drop_inode() which are already stale on the stock kernel, I opted to not touch them. This ties into an effort to remove the I_WILL_FREE flag, unblocking other work. If accepted would be probably best taken through vfs branches with said work, see https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git/log/?h=vfs-6.18.inode.refcount.preliminaries fs/ocfs2/inode.c | 23 ++--------------------- fs/ocfs2/inode.h | 1 - fs/ocfs2/ocfs2_trace.h | 2 -- fs/ocfs2/super.c | 2 +- 4 files changed, 3 insertions(+), 25 deletions(-) diff --git a/fs/ocfs2/inode.c b/fs/ocfs2/inode.c index 6c4f78f473fb..5f4a2cbc505d 100644 --- a/fs/ocfs2/inode.c +++ b/fs/ocfs2/inode.c @@ -1290,6 +1290,8 @@ static void ocfs2_clear_inode(struct inode *inode) void ocfs2_evict_inode(struct inode *inode) { + write_inode_now(inode, 1); + if (!inode->i_nlink || (OCFS2_I(inode)->ip_flags & OCFS2_INODE_MAYBE_ORPHANED)) { ocfs2_delete_inode(inode); @@ -1299,27 +1301,6 @@ void ocfs2_evict_inode(struct inode *inode) ocfs2_clear_inode(inode); } -/* Called under inode_lock, with no more references on the - * struct inode, so it's safe here to check the flags field - * and to manipulate i_nlink without any other locks. */ -int ocfs2_drop_inode(struct inode *inode) -{ - struct ocfs2_inode_info *oi = OCFS2_I(inode); - - trace_ocfs2_drop_inode((unsigned long long)oi->ip_blkno, - inode->i_nlink, oi->ip_flags); - - assert_spin_locked(&inode->i_lock); - inode->i_state |= I_WILL_FREE; - spin_unlock(&inode->i_lock); - write_inode_now(inode, 1); - spin_lock(&inode->i_lock); - WARN_ON(inode->i_state & I_NEW); - inode->i_state &= ~I_WILL_FREE; - - return 1; -} - /* * This is called from our getattr. */ diff --git a/fs/ocfs2/inode.h b/fs/ocfs2/inode.h index accf03d4765e..07bd838e7843 100644 --- a/fs/ocfs2/inode.h +++ b/fs/ocfs2/inode.h @@ -116,7 +116,6 @@ static inline struct ocfs2_caching_info *INODE_CACHE(struct inode *inode) } void ocfs2_evict_inode(struct inode *inode); -int ocfs2_drop_inode(struct inode *inode); /* Flags for ocfs2_iget() */ #define OCFS2_FI_FLAG_SYSFILE 0x1 diff --git a/fs/ocfs2/ocfs2_trace.h b/fs/ocfs2/ocfs2_trace.h index 54ed1495de9a..4b32fb5658ad 100644 --- a/fs/ocfs2/ocfs2_trace.h +++ b/fs/ocfs2/ocfs2_trace.h @@ -1569,8 +1569,6 @@ DEFINE_OCFS2_ULL_ULL_UINT_EVENT(ocfs2_delete_inode); DEFINE_OCFS2_ULL_UINT_EVENT(ocfs2_clear_inode); -DEFINE_OCFS2_ULL_UINT_UINT_EVENT(ocfs2_drop_inode); - TRACE_EVENT(ocfs2_inode_revalidate, TP_PROTO(void *inode, unsigned long long ino, unsigned int flags), diff --git a/fs/ocfs2/super.c b/fs/ocfs2/super.c index 53daa4482406..e4b0d25f4869 100644 --- a/fs/ocfs2/super.c +++ b/fs/ocfs2/super.c @@ -129,7 +129,7 @@ static const struct super_operations ocfs2_sops = { .statfs = ocfs2_statfs, .alloc_inode = ocfs2_alloc_inode, .free_inode = ocfs2_free_inode, - .drop_inode = ocfs2_drop_inode, + .drop_inode = generic_delete_inode, .evict_inode = ocfs2_evict_inode, .sync_fs = ocfs2_sync_fs, .put_super = ocfs2_put_super, -- 2.43.0
