Actually the path parameter is not used in this function at all, I'd say just remove it. > { > int i; > int ret = 0;> diff --git a/cmds-fi-usage.c b/cmds-fi-usage.c > index de7ad668..9a1c76ab 100644 > --- a/cmds-fi-usage.c > +++ b/cmds-fi-usage.c > @@ -227,7 +227,7 @@ static int cmp_btrfs_ioctl_space_info(const void *a, > const void *b) > /* > * This function load all the information about the space usage > */ > -static struct btrfs_ioctl_space_args *load_space_info(int fd, char *path) > +static struct btrfs_ioctl_space_args *load_space_info(int fd, const char > *path) > { > struct btrfs_ioctl_space_args *sargs = NULL, *sargs_orig = NULL; > int ret, count; > @@ -305,7 +305,7 @@ static void get_raid56_used(struct chunk_info *chunks, > int chunkcount, > #define MIN_UNALOCATED_THRESH SZ_16M > static int print_filesystem_usage_overall(int fd, struct chunk_info > *chunkinfo, > int chunkcount, struct device_info *devinfo, int devcount, > - char *path, unsigned unit_mode) > + const char *path, unsigned unit_mode) > { > struct btrfs_ioctl_space_args *sargs = NULL; > int i; > @@ -931,7 +931,7 @@ static void _cmd_filesystem_usage_linear(unsigned > unit_mode, > static int print_filesystem_usage_by_chunk(int fd, > struct chunk_info *chunkinfo, int chunkcount, > struct device_info *devinfo, int devcount, > - char *path, unsigned unit_mode, int tabular) > + const char *path, unsigned unit_mode, int tabular) > { > struct btrfs_ioctl_space_args *sargs; > int ret = 0; > diff --git a/cmds-rescue.c b/cmds-rescue.c > index c40088ad..c61145bc 100644 > --- a/cmds-rescue.c > +++ b/cmds-rescue.c > @@ -32,8 +32,8 @@ static const char * const rescue_cmd_group_usage[] = { > NULL > }; > > -int btrfs_recover_chunk_tree(char *path, int verbose, int yes); > -int btrfs_recover_superblocks(char *path, int verbose, int yes); > +int btrfs_recover_chunk_tree(const char *path, int verbose, int yes); That path argument is being passed to recover_prepare which can alo use a const to its path parameter > +int btrfs_recover_superblocks(const char *path, int verbose, int yes); > > static const char * const cmd_rescue_chunk_recover_usage[] = { > "btrfs rescue chunk-recover [options] <device>", > diff --git a/send-utils.c b/send-utils.c > index b5289e76..8ce94de1 100644 > --- a/send-utils.c > +++ b/send-utils.c > @@ -28,8 +28,8 @@ > #include "ioctl.h" > #include "btrfs-list.h" > > -static int btrfs_subvolid_resolve_sub(int fd, char *path, size_t *path_len, > - u64 subvol_id); > +static int btrfs_subvolid_resolve_sub(int fd, char *path, > + size_t *path_len, u64 subvol_id); This seems like an unrelated change. As a matter of fact btrfs_subvolid_resolve_sub is used only by btrfs_subvolid_resolve. So if you move the latter after the former then you can drop the declaration at the beginning of the file altogether. > > static int btrfs_get_root_id_by_sub_path(int mnt_fd, const char *sub_path, > u64 *root_id) > -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
