Hi, FILE: fs/ubifs/misc.h : FUNCTION : ubifs_compr_present "ubifs_compr_present" function has "ubifs_assert" which checks for the valid compression value and does a stack_dump if not. Could there be a case where the "compr_type" is corrupt; if yes, then does a stack_dump suffice? Thus if compr_type is invalid then the below return is not reliable. return !!ubifs_compressors[compr_type]->capi_name; So where does this end, eventually does it go to a point where the volume get corrupt and not unmountable ? Cheers
