From 2c6b6b1029d46a8760d6cba09b4e75cb1ac9b579 Mon Sep 17 00:00:00 2001 From: Ajay Kaher Date: Fri, 28 Jul 2023 23:50:45 +0530 Subject: [PATCH] tracefs: Rename and export some tracefs functions Export a few tracefs functions that will be needed by the eventfs dynamic file system. Rename them to start with "tracefs_" to keep with the name space. start_creating -> tracefs_start_creating failed_creating -> tracefs_failed_creating end_creating -> tracefs_end_creating Link: https://lkml.kernel.org/r/1690568452-46553-4-git-send-email-akaher@vmware.com Signed-off-by: Ajay Kaher Co-developed-by: Steven Rostedt (VMware) Signed-off-by: Steven Rostedt (VMware) Tested-by: Ching-lin Yu Signed-off-by: Steven Rostedt (Google) --- fs/tracefs/inode.c | 20 ++++++++++---------- fs/tracefs/internal.h | 5 +++++ 2 files changed, 15 insertions(+), 10 deletions(-) diff --git a/fs/tracefs/inode.c b/fs/tracefs/inode.c index 2508944..4acc4b4 100644 --- a/fs/tracefs/inode.c +++ b/fs/tracefs/inode.c @@ -147,7 +147,7 @@ static const struct inode_operations tracefs_dir_inode_operations = { .rmdir = tracefs_syscall_rmdir, }; -static struct inode *tracefs_get_inode(struct super_block *sb) +struct inode *tracefs_get_inode(struct super_block *sb) { struct inode *inode = new_inode(sb); if (inode) { @@ -422,7 +422,7 @@ static struct file_system_type trace_fs_type = { }; MODULE_ALIAS_FS("tracefs"); -static struct dentry *start_creating(const char *name, struct dentry *parent) +struct dentry *tracefs_start_creating(const char *name, struct dentry *parent) { struct dentry *dentry; int error; @@ -460,7 +460,7 @@ static struct dentry *start_creating(const char *name, struct dentry *parent) return dentry; } -static struct dentry *failed_creating(struct dentry *dentry) +struct dentry *tracefs_failed_creating(struct dentry *dentry) { inode_unlock(d_inode(dentry->d_parent)); dput(dentry); @@ -468,7 +468,7 @@ static struct dentry *failed_creating(struct dentry *dentry) return NULL; } -static struct dentry *end_creating(struct dentry *dentry) +struct dentry *tracefs_end_creating(struct dentry *dentry) { inode_unlock(d_inode(dentry->d_parent)); return dentry; @@ -513,14 +513,14 @@ struct dentry *tracefs_create_file(const char *name, umode_t mode, if (!(mode & S_IFMT)) mode |= S_IFREG; BUG_ON(!S_ISREG(mode)); - dentry = start_creating(name, parent); + dentry = tracefs_start_creating(name, parent); if (IS_ERR(dentry)) return NULL; inode = tracefs_get_inode(dentry->d_sb); if (unlikely(!inode)) - return failed_creating(dentry); + return tracefs_failed_creating(dentry); inode->i_mode = mode; inode->i_fop = fops ? fops : &tracefs_file_operations; @@ -529,13 +529,13 @@ struct dentry *tracefs_create_file(const char *name, umode_t mode, inode->i_gid = d_inode(dentry->d_parent)->i_gid; d_instantiate(dentry, inode); fsnotify_create(d_inode(dentry->d_parent), dentry); - return end_creating(dentry); + return tracefs_end_creating(dentry); } static struct dentry *__create_dir(const char *name, struct dentry *parent, const struct inode_operations *ops) { - struct dentry *dentry = start_creating(name, parent); + struct dentry *dentry = tracefs_start_creating(name, parent); struct inode *inode; if (IS_ERR(dentry)) @@ -543,7 +543,7 @@ static struct dentry *__create_dir(const char *name, struct dentry *parent, inode = tracefs_get_inode(dentry->d_sb); if (unlikely(!inode)) - return failed_creating(dentry); + return tracefs_failed_creating(dentry); /* Do not set bits for OTH */ inode->i_mode = S_IFDIR | S_IRWXU | S_IRUSR| S_IRGRP | S_IXUSR | S_IXGRP; @@ -557,7 +557,7 @@ static struct dentry *__create_dir(const char *name, struct dentry *parent, d_instantiate(dentry, inode); inc_nlink(d_inode(dentry->d_parent)); fsnotify_mkdir(d_inode(dentry->d_parent), dentry); - return end_creating(dentry); + return tracefs_end_creating(dentry); } /** diff --git a/fs/tracefs/internal.h b/fs/tracefs/internal.h index 954ea00..7dfb7eb 100644 --- a/fs/tracefs/internal.h +++ b/fs/tracefs/internal.h @@ -12,4 +12,9 @@ static inline struct tracefs_inode *get_tracefs(const struct inode *inode) { return container_of(inode, struct tracefs_inode, vfs_inode); } + +struct dentry *tracefs_start_creating(const char *name, struct dentry *parent); +struct dentry *tracefs_end_creating(struct dentry *dentry); +struct dentry *tracefs_failed_creating(struct dentry *dentry); +struct inode *tracefs_get_inode(struct super_block *sb); #endif /* _TRACEFS_INTERNAL_H */ -- 2.7.4
