Name:path_put - put a reference to a path*@path: path to put the reference to* Given a path decrement the reference count to the dentry and the vfsmount.

Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
const struct path * | path |
Name | Describe |
---|---|
audit_add_watch | Find a matching watch entry, or add this one.* Caller must hold audit_filter_mutex. |
audit_alloc_mark | |
audit_trim_trees | |
audit_add_tree_rule | alled with audit_filter_mutex |
audit_tag_tree | |

bpf_prog_offload_info_fill | |
bpf_map_offload_info_fill | |
perf_fill_ns_link_info | |
free_filters_list | |
big_key_destroy | dispose of the data dangling from the corpse of a big_key key |
tomoyo_policy_loader_exists | moyo_policy_loader_exists - Check whether /sbin/tomoyo-init exists.* Returns true if /sbin/tomoyo-init exists, false otherwise. |
tomoyo_mount_acl | moyo_mount_acl - Check permission for mount() operation.*@r: Pointer to "struct tomoyo_request_info".*@dev_name: Name of device file. Maybe NULL.*@dir: Pointer to "struct path".*@type: Name of filesystem type.*@flags: Mount options. |
tomoyo_realpath_nofollow | moyo_realpath_nofollow - Get realpath of a pathname.*@pathname: The pathname to solve.* Returns the realpath of @pathname on success, NULL otherwise. |
d_namespace_path | d_namespace_path - lookup a name associated with a given path*@path: path to lookup (NOT NULL)*@buf: buffer to store path to (NOT NULL)*@name: Returns - pointer for start of path name with in @buf (NOT NULL)*@flags: flags controlling path |
aa_bind_mount | |
aa_move_mount | |
aa_new_mount | |
do_faccessat | access() needs to use the real uid/gid, not the effective uid/gid.* We do this by temporarily clearing all FS-related capabilities and* switching the fsuid/fsgid around to the real ones. |
ksys_chdir | |
ksys_chroot | |
do_fchmodat | |
do_fchownat | |
do_dentry_open | |
alloc_file_pseudo | |
vfs_statx | vfs_statx - Get basic and extra attributes by filename*@dfd: A file descriptor representing the base dir for a relative filename*@filename: The name of the file of interest*@flags: Flags to control the query*@stat: The result structure to fill in |
do_readlinkat | |
terminate_walk | |
nd_jump_root | |
nd_jump_link | Helper to directly jump to a known parsed path from ->get_link,* caller must have taken a reference to path beforehand. |
put_link | |
follow_automount | Perform an automount* - return -EISDIR to tell follow_managed() to stop and return the path we* were called with. |
pick_link | |
kern_path_locked | does lookup, returns the object with parent locked |
do_tmpfile | |
do_o_path | |
filename_create | |
done_path_create | |
do_rmdir | |
do_unlinkat | Make sure that the actual truncation of the file will occur outside its* directory's i_mutex. Truncate can take a long time if there is a lot of* writeout happening, and we don't want to prevent access to the directory* while waiting on the I/O. |
do_linkat | Hardlinks are often used in delicate situations. We avoid* security-related surprises by not following symlinks on the* newname. --KAB* We don't follow them on the oldname either to be compatible* with linux 2.0, and to avoid hard-linking to directories |
do_renameat2 | |
lock_mount | |
do_loopback | do loopback mount. |
SYSCALL_DEFINE3 | |
do_move_mount_old | |
do_mount | Flags is a 32-bit value that allows up to 31 non-fs dependent flags to* be given to the mount() call (ie: read-only, no-dev, no-suid etc) |
SYSCALL_DEFINE3 | Create a kernel mount representation for a new, prepared superblock* (specified by fs_fd) and attach to an open_tree-like file descriptor. |
SYSCALL_DEFINE5 | Move a mount from one place to another. In combination with* fsopen()/fsmount() this is used to install a new mount and in combination* with open_tree(OPEN_TREE_CLONE [| AT_RECURSIVE]) it can be used to copy* a mount subtree. |
SYSCALL_DEFINE2 | pivot_root Semantics:* Moves the root file system of the current process to the directory put_old,* makes new_root as the new root file system of the current process, and sets* root/cwd of all processes which had them on the current root to new_root |
current_chrooted | |

path_setxattr | |
path_getxattr | |
path_listxattr | |
path_removexattr | |
do_utimes | do_utimes - change times on filename or file descriptor*@dfd: open file descriptor, -1 or AT_FDCWD*@filename: path name or NULL*@times: new times or NULL*@flags: zero or more flags (only AT_SYMLINK_NOFOLLOW for the moment)* If filename is NULL and dfd |
set_fs_root | Replace the fs->{rootmnt,root} with {mnt,dentry}. Put the old values.* It can block. |
set_fs_pwd | Replace the fs->{pwdmnt,pwd} with {mnt,dentry}. Put the old values.* It can block. |
chroot_fs_refs | |

user_statfs | |
open_related_ns | |
fs_lookup_param | s_lookup_param - Look up a path referred to by a parameter*@fc: The filesystem context to log errors through.*@param: The parameter.*@want_bdev: T if want a blockdev*@_path: The result of the lookup |
SYSCALL_DEFINE3 | Pick a superblock into a context for reconfiguration. |
lookup_bdev | lookup_bdev - lookup a struct block_device by name*@pathname: special file representing the block device* Get a reference to the blockdevice at @pathname in the current* namespace if possible and return it. Return ERR_PTR(error)* otherwise. |
mounts_open_common | |
mounts_release | |
inotify_find_inode | d_inode - resolve a user-given path to a specific inode |

SYSCALL_DEFINE5 | sys_name_to_handle_at: convert name to handle*@dfd: directory relative to which name is interpreted if not absolute*@name: name that should be converted to handle |
do_handle_open | |
kernel_quotactl | This is the system call interface. This communicates with* the user-level programs. Currently this only supports diskquota* calls. Maybe we need to add the process quotas etc. in the future,* but we probably should use rlimits for that. |
