Can you take this opportunity to rename it to either 'fh' or 'priv'? It's a bit of yak shaving, but not too difficult so it will be addressed in the next version (Jacopo already wrote the patches, thanks). > Generally it's not a good idea to prefix variables with __ for no good reason. > > Grepping for __fh also shows two other drivers: > > drivers/media/platform/chips-media/coda/coda-common.c:#define fh_to_ctx(__fh) container_of(__fh, struct coda_ctx, fh) > drivers/media/platform/samsung/s5p-mfc/s5p_mfc_common.h:#define fh_to_ctx(__fh) container_of(__fh, struct s5p_mfc_ctx, fh) > > I think it is a good idea to rename __fh to fh there as well. That can't be done, otherwise things like #define fh_to_ctx(fh) container_of(fh, struct coda_ctx, fh) static inline struct coda_ctx *file_to_ctx(struct file *filp) { return fh_to_ctx(file_to_v4l2_fh(filp)); } will expand in the file_to_ctx() function to return container_of(file_to_v4l2_fh(filp), struct coda_ctx, file_to_v4l2_fh(filp)) We could rename the __fh argument to vfh or v4l2fh, but I think __fh is equally good there.
